Question: how to put together a scuba regulator

 Setting up the  Regulators
The first stage regulator drops the tank pressure (3500+/-  PSI) to 100 to 150 PSI. This depends what brand of regulator you buy. Each brand  has its own designed working pressure. For this reason, I buy two of the same  make and model regulator units. I will  start by calling the Regulator assembles Octopus units. An Octopus is made up by a first stage regulator, second  stage regulator, high pressure hose with gage and a BCD inflator hose. You will need to add a second BCD inflator  hose to one of the octopus units. Air Balance Process
This Air balance System connects the tank systems together at the low pressure side. Diving on Dual Tanks
Start with the Octopus unit with  the second BCD inflator hose. This Octopus unit is please on the tank that is  on the same side of the BCD inflator value.

 Pick up the BCD by its handle or shoulder straps and make sure the cylinder is securely fastened and does not slip. Attaching The Regulator
The following procedures are for attaching a yoke style regulator to a "J" or "K" cylinder valve. Remove the dust cap by loosening the yoke screw. Place the 1st stage over the cylinder valve. The 1st stage's filter should be positioned against the valve's o-ring, and the 2nd stage hoses should be on the same side as the valve knob. Tighten the yoke screw against the valve. The screw should only be tightened finger-tight. Don't worry if the 1st stage rotates on the valve. It will tighten up when the air is opened. Attach the low-pressure hose to the power inflator's air inlet.

 Make sure the 2nd stages are placed on top of the BCD to prevent damage from the cylinder or a passing diver. Special care must be taken when placing a scuba unit on a beach because sand can cause your regulator or power inflator to malfunction. A towel or tarp underneath your equipment is very useful for this purpose. Secure the scuba units or lay them down after assembly. Disassembling Your Scuba Unit
You disassemble the scuba unit in the opposite order the gear was assembled. However, a couple steps are added to the process. Turn the valve knob clockwise until it's completely closed. Press the 2nd stage's purge button to release all the air pressure from the hoses. Remove the low-pressure hose from the power inflator. Remove the 1st stage from the cylinder valve.

 Newbie divers might find this a little tricky, but keep practicing and you’ll be bossing it in no time. First, the tank needs to be attached to your BCD (Buoyancy Control Device), using the straps at the back of the bcd. Next, connect the first stage of the scuba regulator to the cylinder valve of the oxygen tank. ( You can read more about the first stage in the next section!) This is achieved with the first stage of the scuba regulator, located at the end of the scuba octopus; where all four parts meet. To connect the regulator first stage to the oxygen tank: Remove tank valve cover. Unscrew the metal knob of the regulator first stage and remove the dust cover. As you do this, make sure the regulators second stage is on the right hand side of the bcd and the gauge is on the left hand side.

 This comes with a Yoke Screw which tightens the regulator onto the tank. A Dust Cap is a small rubber cap which is positioned over the regulator first stage opening and tightened down using the yoke screw. This dust cap is crucial for preventing water from entering the regulator first stage body. Ports and Port Plugs are found all over the first stage body. These are where the different hoses are attached to. If the port is not in use, it will be covered by a port plug. There are often more ports than what is actually needed, so you can position the hoses in the way they like. Primary Second Stage
This is the part of the setup which the diver puts in their mouth and breathes from. This part is attached to the first stage by the LP hose. This part of the regulator works as the second phase of air pressure reduction, and transforms the air into a breathable ambient pressure.

All of the mechanisms which lower the air pressure to an intermediate pressure are housed in the first stage body. This is a metal cylinder through which the air enters, the pressure is reduced, and then leaves to go through the second stage. This could also be considered the “end of the octopus” as it’s where the 2 regulators, dive gauge and pressure hose all come together.

 The purge button is found on the face of the regulators second stage. This button allows the second stage to flood with air, forcing any water out of the second stage. The ease of breathing adjustment is found on most regulators, and it allows divers to adjust their breathing resistance through a knob or lever. This adjustment helps to avoid free flow, which is when the air flows continuously out of the second stage regardless of the diver’s breath. An exhaust valve is located on the second stage and works to channel any exhaled air bubbles away from the divers face. This is found below the mouthpiece and helps you to keep a clear vision. Then there is the mouthpiece. This is the part that the diver puts their mouth on to access air. Alternate Second Stage
This part of the scuba octopus setup, also called a buddy regulator or an alternate air source, is basically the same thing as the primary second stage. It does the same job through the same process as the primary second stage, however, it is used as a backup.

In the case of emergency, such as a fellow diver running out of air, the alternate second stage can be used to allow them to share from your air tank. This part is also attached to the first stage with a LP regulator hose. This part of the scuba octopus setup works exactly the same way as the primary second stage. While it consists of the same parts, it is connected by a low pressure hose. An LP hose transports the intermediate air from the first to the second stage.

While it consists of the same parts, it is connected by a low pressure hose. An LP hose transports the intermediate air from the first to the second stage.

#1 Attaching Regulator to Scuba Tank
Once you have your scuba octopus ready, you’ll want to safely and securely attach it to your scuba / oxygen tank. Newbie divers might find this a little tricky, but keep practicing and you’ll be bossing it in no time. First, the tank needs to be attached to your BCD (Buoyancy Control Device), using the straps at the back of the bcd. Next, connect the first stage of the scuba regulator to the cylinder valve of the oxygen tank. ( You can read more about the first stage in the next section!) This is achieved with the first stage of the scuba regulator, located at the end of the scuba octopus;

The regulator's second stage consists of: Plastic chamber with an outer rubber diaphragm that is in contact with ambient water pressure
Purge button
Inner valve that is connected to a movable lever
Exhaust valve
Mouthpiece
The second stage is connected by a hose to the intermediate-pressure chamber of the first stage. This is how the second stage operates: You inhale, thereby lowering the pressure within the second stage to below the ambient water pressure. The water pressure presses in on the diaphragm membrane and moves the lever. The lever's movement opens the inlet valve. This allows air to flow into the second stage from the first stage, and into your lungs through the mouthpiece. When you exhale, the pressure in the second stage exceeds the ambient water pressure and pushes out on the membrane.

All of the mechanisms which lower the air pressure to an intermediate pressure are housed in the first stage body. This is a metal cylinder through which the air enters, the pressure is reduced, and then leaves to go through the second stage. This could also be considered the “end of the octopus” as it’s where the 2 regulators, dive gauge and pressure hose all come together.

The Regulator Second Stage:
 Since the ambient pressure changes as a diver changes depth, scuba diving regulators must adjust the air delivered to ambient pressure as a diver ascends and descends. How Regulators Work
Scuba regulators reduce tank pressure in two steps. The first step of pressure reduction is from tank pressure to intermediate pressure, and the second step of pressure reduction is from intermediate pressure to ambient pressure. The Regulator First Stage: The first stage reduces air at tank pressure to intermediate pressure and releases the intermediate pressure air into a hose which feeds into the regulator's second stage. The way the regulator first stage reduces tank pressure is ingenious. A first stage consists of two air chambers separated by a valve. When the regulator is not pressurized this valve is open. When connected to a tank, air from the scuba tank flows into the first chamber, through the valve, and into the second chamber. The valve between the two chambers stays open until the air in the second chamber reaches intermediate pressure.

 3. Yoke Screw
The regulator's yoke is equipped with a yoke screw-- a metal screw that runs through the regulator yoke and tightens the regulator first stage body onto the tank. To tighten the yoke screw, the diver turns the black, plastic handle attached to the screw. 4. Dust Cap
It is extremely important that no water enters the regulator first stage body. When the first stage body is tightened onto a tank, it creates a water-tight seal to the tank valve. However, when the first stage body is disconnected from the tank, it is possible for water to enter the opening in the first stage, through which air passes from the tank to the regulator. The dust cap is a rubber cap that can be placed over the regulator first stage opening and tightened down using the regulator yoke screw. This seals closed the opening on the first stage. 5.

 Divers then rely on scuba regulators to decrease the stored high-pressure air to a much safer pressure level every time they inhale through the connected mouthpiece. Parts of a Scuba Diving Regulator
Scuba regulators do the critical job of delivering breathable air from pressurized air tanks to divers by working in two stages: First Stage Regulator
As mentioned above, air is compressed and stored in the tank under high pressure, usually about 3,000 pounds per square inch (psi). In order to reduce this pressure, the regulator first stage, which attaches to the tank valve, lowers the tank pressure to intermediate pressure (about 140psi) for release into a hose that leads to the regulator’s second stage. The valve in the first stage opens to let some air into the hose and then closes again. The exact process, of course, also depends on your scuba tank’s valve type. The regulator also compensates for the decreased pressure in the tank as the air is used and as the diver changes depth, which changes the ambient water pressure. Second Stage Regulator
The second stage of a scuba regulator is the part that goes into your mouth. It contains a mechanism that further reduces the intermediate pressure in the hose coming from the first stage to the surrounding water pressure, making it comfortable and easy to breathe. As with the first stage, the second stage also contains a piston or diaphragm construction which starts and stops the airflow.

The first SCUBA (self-contained underwater breathing apparatus) was developed in the early 1940s by French divers Emile Gagnan and Jacques Cousteau (the latter went on to become a famous conservationist and filmmaker). It was patented in 1945 and called the Aqua Lung. ( BestReviews)
A good scuba regulator is a vital part of any dive gear, reducing the high pressure combination of helium, nitrogen, and oxygen in the tanks so it’s breathable by the diver. Not all regulators are the same, however, so we’ve put together a concise buyer’s guide to help those new to the sport decide which is best. We’ve also made a few recommendations at the end of this article. Our top pick is the outstanding Scubapro MK25 EVO/A700 Diving Regulator System, a combination that provides safety and easy breathing for experienced divers wherever they go and whatever conditions they encounter. How scuba regulators work
Scuba regulators are divided into first stage — which takes tank pressure down from a couple thousand pounds per square inch (psi) to around 140 psi — and second stage, the mouthpiece, which offers fine pressure adjustment for comfortable breathing. You may also have an octopus, or a standby second regulator for emergencies. Advertisement
The first-stage regulator is more complex. They are either diaphragm or piston operated.

 When purchasing your regulator you will need to buy the three major parts – the 1st and 2nd stage (regulator set), the alternate air source (octopus) and the instruments. As with most purchases, going for major brand names assures a certain level of quality and even though many of us like a bargain, with scuba equipment, the more you spend the better the equipment you get. So, if you thought your regulator would include an octopus and gauges, take your regulator budget and deduct between 30% to 40% to allow for the basic instruments you will need. Whatever is left is what you can afford for your regulator. You should always use the same brand of 1st and 2nd stages, plus the octopus you choose should also be from the same manufacturer as your first stage regulator to ensure the intermediate pressures are compatible. Gauges need not be made by the same manufacturer, but you should always go for major instrument brands because their accuracy and reliability are much higher than imitations. Free Assembly
When you have made your choice and ordered your equipment from The Scuba Doctor, we will assemble and test the regulator, octopus, gauges and any hoses, prior to dispatch or collection to ensure they are functioning correctly (unless you request us to do otherwise). Scuba Regulator Choices
There are several types of regulator, piston or diaphragm and balanced and unbalanced systems. DIN vs Yoke (A-Clamp) Regulators
The most common coupling in use in Australia is still the International Yoke or A-Clamp fitting (same thing, different names!). Yoke fittings were the recreational diving worldwide standard, but technical divers switched to DIN a long time ago because it's a safer system.

The Regulator Second Stage:
 The first stage of a scuba diving regulator is the part of the regulator that attaches to the tank valve. Second Stage: The second stage of a scuba diving regulator is the part that the diver puts into his mouth. Tank Pressure: The pressure of the air in a scuba tank. Air inside a tank is compressed to a very high pressure in order to carry an adequate supply of breathing gas for a scuba dive. For a frame of reference, pneumatic tools such as those used by mechanics commonly operate at 90 - 140 psi. A full scuba tank is often pressurized to 3000 psi. Intermediate Pressure: The pressure of the air output from the first stage and sent to the second stage.

The first stage of a scuba diving regulator is the part of the regulator that attaches to the tank valve. Second Stage: The second stage of a scuba diving regulator is the part that the diver puts into his mouth. Tank Pressure: The pressure of the air in a scuba tank. Air inside a tank is compressed to a very high pressure in order to carry an adequate supply of breathing gas for a scuba dive. For a frame of reference, pneumatic tools such as those used by mechanics commonly operate at 90 - 140 psi. A full scuba tank is often pressurized to 3000 psi. Intermediate Pressure: The pressure of the air output from the first stage and sent to the second stage.

 The first stage of a regulator attaches directly to the tank, reducing the pressure of the air leaving the tank by a preset amount. The second stage reduces the pressure yet again, bringing it down to ambient pressure, where you'll be able to breathe air comfortably. There are a number of options for both stages, including ports for pressure gauges, low pressure inflator hoses, and dry suit hoses. You can also choose whether or not the first stage of the regulator is balanced or unbalanced - the advantage of a balanced first stage is that it allows you to breathe just as easily at low tank pressures, or at depths of up to 90ft. With multiple options for adjustment knobs, air flow dials, and the like, you'll always be able to alter the regulator's flow rate to compensate for any changes in depth.

 The exact process, of course, also depends on your scuba tank’s valve type. The regulator also compensates for the decreased pressure in the tank as the air is used and as the diver changes depth, which changes the ambient water pressure. Second Stage Regulator
The second stage of a scuba regulator is the part that goes into your mouth. It contains a mechanism that further reduces the intermediate pressure in the hose coming from the first stage to the surrounding water pressure, making it comfortable and easy to breathe. As with the first stage, the second stage also contains a piston or diaphragm construction which starts and stops the airflow. The mouthpiece, exhaust valve, and an emergency purge valve (or button) are all part of the second stage of the scuba regulator. The exhaust valve lets the air escape into the water when you exhale. It is a one-way valve and does not allow water to enter from the outside. When the purge button (usually the front cover of the second stage in modern models) is pushed, it forces air to flow continuously into the second stage chamber forcing any water out of the mouthpiece through the exhaust valve. With this mechanism, divers are actually able to vomit while holding the second stage in their mouths instead of pulling it out and risking accidental water inhalation.

 Scuba systems that were invented before the Aqua-Lung were closed circuit, or rebreather, equipment, in which breathing gas flows through an ambient pressure circuit to the diver, and exhaled gas is returned through a scrubber which removes carbon dioxide, to a volume bag (or counter-lung), some fresh gas is added to maintain the oxygen content, and then back to the diver again, in a closed loop, or open circuit free-flow systems, in which the air is supplied at an approximately constant rate, and the diver uses only a relatively small part of the passing gas. The first and second stage mechanisms of the regulator are packaged in a circular metal housing mounted on the cylinder valve behind the diver's neck. To prevent free-flow, the exhaust valve must be at the same depth as the diaphragm, and the only reliable place to do this is in the same housing. The air flows through a pair of large bore corrugated rubber hoses to and from the mouthpiece. The supply hose is connected to one side of the regulator body and supplies air to the mouthpiece through a non-return valve, and the exhaled air is returned to the regulator housing on the outside of the diaphragm, also through a non-return valve on the other side of the mouthpiece and through another non-return exhaust valve in the regulator housing. A non-return valve is fitted to each of the breathing hoses where they connect to the mouthpiece to prevent any water that gets into the mouthpiece from going into the inhalation hose, and ensures that once it is blown into the exhalation hose that it cannot flow back. This slightly increases the flow resistance of air, but makes the regulator easier to clear. Ideally the delivered pressure is equal to the resting pressure in the diver's lungs as this is what human lungs are adapted to breathe. With a twin hose regulator behind the diver at shoulder level, the delivered pressure changes with diver orientation. if the diver rolls on his or her back the released air pressure is higher than in the lungs.

A scuba diving regulator is the piece of equipment that enables a diver to breathe from a scuba tank. The regulator is so named because it regulates the pressure of the air a diver breathes. The compressed air inside a scuba tank is at an extremely high pressure, which could injure a diver who tries to breathe directly from the tank, and the regulator is necessary to reduce the pressure of the compressed air to a pressure the diver can breathe. To accomplish this, a regulator reduces air pressure in two steps, or stages--first, from the pressure in the tank to an intermediate pressure; and second, from the intermediate pressure to a pressure that the divers can safely breathe. In it's most basic form, a scuba regulator consists of two parts: a mechanism that accomplishes the first stage of pressure reduction (called  first stage) and a mechanism that accomplishes the second stage of pressure reduction (called second stage ). However, contemporary scuba diving regulators usually incorporate a variety of additional accessories. 01

 To help ensure your safety, as well as the proper use of your scuba diving equipment, it helps to know exactly how a scuba regulator works. How Does a Scuba Regulator Work? Scuba diving is essentially about being able to stay in the water—and at greater depths—for a long time. You’ll obviously need a lot of breathable air, but storing it in its basic form won’t allow you to last long underwater. The only way that more air can be brought with you underwater is to pressurize and compress it inside cylinder tanks. Divers then rely on scuba regulators to decrease the stored high-pressure air to a much safer pressure level every time they inhale through the connected mouthpiece. Parts of a Scuba Diving Regulator
Scuba regulators do the critical job of delivering breathable air from pressurized air tanks to divers by working in two stages: First Stage Regulator
As mentioned above, air is compressed and stored in the tank under high pressure, usually about 3,000 pounds per square inch (psi). In order to reduce this pressure, the regulator first stage, which attaches to the tank valve, lowers the tank pressure to intermediate pressure (about 140psi) for release into a hose that leads to the regulator’s second stage. The valve in the first stage opens to let some air into the hose and then closes again.

 When the first stage body is tightened onto a tank, it creates a water-tight seal to the tank valve. However, when the first stage body is disconnected from the tank, it is possible for water to enter the opening in the first stage, through which air passes from the tank to the regulator. The dust cap is a rubber cap that can be placed over the regulator first stage opening and tightened down using the regulator yoke screw. This seals closed the opening on the first stage. 5. Port/ Port Plug
Regulator first stage bodies have multiple openings, or ports, that regulator hoses can be screwed into. Usually, regulators have more ports than the standard number of hoses, which allows divers to position their hoses in a variety of configurations. These openings are called ports, and the plugs that close the regulator ports when they are not in use are called port plugs . 03

The regulator second stage is the part of the scuba diving regulator that a diver actually breathes from.

 4. Submersible Pressure Gauge and Gauge Console
The submersible pressure gauge (also called a pressure gauge or SPG) allows a diver to monitor the amount of air in his scuba tank so that he doesn't run out of air underwater. The pressure gauge is connected to the regulator first stage by a high-pressure hose (HP hose) that feeds high-pressure air from the tank directly to the pressure gauge. Frequently, the console containing the pressure gauge also holds a variety of other gauges, such as a depth gauge, compass, or dive computer. 5. Low-Pressure Inflator Hose

The basic rule of thumb with selecting a diving regulator is to go for the most expensive you can afford that is most suited to the diving you will be doing. The more you spend the easier it will be to breathe from. When purchasing your regulator you will need to buy the three major parts – the 1st and 2nd stage (regulator set), the alternate air source (octopus) and the instruments. As with most purchases, going for major brand names assures a certain level of quality and even though many of us like a bargain, with scuba equipment, the more you spend the better the equipment you get. So, if you thought your regulator would include an octopus and gauges, take your regulator budget and deduct between 30% to 40% to allow for the basic instruments you will need. Whatever is left is what you can afford for your regulator. You should always use the same brand of 1st and 2nd stages, plus the octopus you choose should also be from the same manufacturer as your first stage regulator to ensure the intermediate pressures are compatible.

Regulator Features - The Scuba Doctor

However, modern regulators all come up to a very high minimum standard so whichever you decide to purchase, you are unlikely to be disappointed. For a large range of Regulator and Octopus options for all conditions visit the Regulators section in the The Scuba Doctor Online Dive Shop. For a large range of Instrument options for all conditions visit the Instruments section in the The Scuba Doctor Online Dive Shop. General Scuba Regulator Guidelines
The basic rule of thumb with selecting a diving regulator is to go for the most expensive you can afford that is most suited to the diving you will be doing. The more you spend the easier it will be to breathe from. When purchasing your regulator you will need to buy the three major parts – the 1st and 2nd stage (regulator set), the alternate air source (octopus) and the instruments. As with most purchases, going for major brand names assures a certain level of quality and even though many of us like a bargain, with scuba equipment, the more you spend the better the equipment you get. So, if you thought your regulator would include an octopus and gauges, take your regulator budget and deduct between 30% to 40% to allow for the basic instruments you will need. Whatever is left is what you can afford for your regulator. You should always use the same brand of 1st and 2nd stages, plus the octopus you choose should also be from the same manufacturer as your first stage regulator to ensure the intermediate pressures are compatible.

Purpose
The diving regulator is a mechanism which reduces the pressure of the supply of breathing gas and provides it to the diver at approximately ambient pressure. The gas may be supplied on demand, when the diver inhales, or as a constant flow past the diver inside the helmet or mask, from which the diver uses what is necessary, while the remainder goes to waste. The gas may be provided directly to the diver, or to a rebreather circuit, to make up for used gas and volume changes due to depth variations. Gas supply may be from a high-pressure scuba cylinder carried by the diver, or from a surface supply through a hose connected to a compressor or high pressure storage system. Types
Open circuit demand valve
A demand valve detects when the diver starts inhaling and supplies the diver with a breath of gas at ambient pressure. When the diver stops inhaling, the demand valve closes to stop the flow. The demand valve has a chamber, which in normal use contains breathing gas at ambient pressure, which is connected to a bite-grip mouthpiece, a full-face mask, or a diving helmet, either direct coupled or connected by a flexible low-pressure hose. On one side of the chamber is a flexible diaphragm to sense the pressure difference between the gas in the chamber on one side and the surrounding water on the other side, and control the operation of the valve which supplies pressurised gas into the chamber. This is done by a mechanical system linking the diaphragm to a valve which is opened to an extent proportional to the displacement of the diaphragm from the closed position. The pressure difference between the inside of the mouthpiece and the ambient pressure outside the diaphragm required to open the valve is known as the cracking pressure.

 The mouthpiece, exhaust valve, and an emergency purge valve (or button) are all part of the second stage of the scuba regulator. The exhaust valve lets the air escape into the water when you exhale. It is a one-way valve and does not allow water to enter from the outside. When the purge button (usually the front cover of the second stage in modern models) is pushed, it forces air to flow continuously into the second stage chamber forcing any water out of the mouthpiece through the exhaust valve. With this mechanism, divers are actually able to vomit while holding the second stage in their mouths instead of pulling it out and risking accidental water inhalation. It’s not pleasant to think about, but what is nice to consider is that this wonderful piece of technology makes it possible to survive underwater—even in the least optimum conditions—until you can safely return to the surface.

You cannot breathe directly out of the tank because the high pressure would damage your lungs. Therefore, the cylinder is fitted with a regulator. The regulator does two things: It reduces the pressure from the tank to a safe level for you to inhale, and it supplies air on-demand. To accomplish these tasks, regulators have two stages: First stage - The first stage attaches to the cylinder. It reduces the pressure from the tank (3000 psi or 204 ATM) to an intermediate pressure (140 psi or 9.5 ATM). Second stage - The second stage is connected to the first stage by a hose.

 The regulator regulates the amount of air that is received by the diver each time he inhales. Because the divers nose is covered by his face mask, air must be inhaled through the divers mouth. There are two types of diving regulators, those designed for SCUBA use and those designed for Hookah applications. A SCUBA regulator is designed for use with SCUBA an air tank, and delivers maximum efficiency when operated at a pressure exceeding 100 p.s.i. They require a "first stage" valve assembly, attached to the SCUBA tank. The function of the first stage is to reduce the extremely high pressure of the air in the SCUBA tank from approximately 2,250 p.s.i. to approximately 180 p.s.i. This pressure then goes to the "second stage," which is the part that is worn in the diver's mouth. The second stage of a SCUBA regulator has a spring loaded "downstream" valve which delivers the correct

A 1964 scuba cylinder valve with reserve, commonly known as a "type J" valve. The inlet is threaded 3/4"-14 NPSM and the outlet is a standard CGA 850 yoke type. The first-stage of the scuba regulator may be connected to the cylinder valve by one of two standard types of fittings. The CGA 850 connector, also known as an international connector, which uses a yoke clamp, or a DIN screw fitting to connect it to the valve of the diving cylinder. There are also European standards for scuba regulator connectors for gases other than air. CGA 850 connection
CGA 850 Yoke connectors (sometimes called A-clamps from their shape) are the most popular regulator connection in North America and several other countries. They clamp the high pressure inlet opening of the regulator against the outlet opening of the cylinder valve, and are sealed by an O-ring in a groove in the contact face of the cylinder valve. The user screws the clamp in place finger-tight to hold the metal surfaces of cylinder valve and regulator first stage in contact, compressing the o-ring between the radial faces of valve and regulator. When the valve is opened, gas pressure presses the O-ring against the outer cylindrical surface of the groove, completing the seal.

 Diving regulators use mechanically operated valves. In most cases there is ambient pressure feedback to both first and second stage, except where this is avoided to allow constant mass flow through an orifice in a rebreather, which requires a constant absolute upstream pressure. Back-pressure regulators are used in gas reclaim systems to conserve expensive helium based breathing gases in surface-supplied diving, and to control the safe exhaust of exhaled gas from built-in breathing systems in hyperbaric chambers . The parts of a regulator are described here as the major functional groups in downstream order as following the gas flow from the cylinder to its final use. Details may vary considerably between manufacturers and models. Contents

Types of diving regulators
Gas pressure regulators are used for several applications in the supply and handling of breathing gases for diving. Pressure reducing regulators are used to reduce gas pressure for supply to the diver in demand and free-flow open circuit breathing apparatus, in rebreather equipment, and in gas blending procedures. Back-pressure regulators are used in the exhaust systems of the built-in breathing systems of diving chambers, and in the recovery of used helium based breathing gas for recycling. Some of these regulators must work underwater, others in the more forgiving conditions of the surface support area. All must work consistently and reliably, but some are parts of safety-critical life-support systems, where a single point of failure must not put lives at risk.

 An Octopus is made up by a first stage regulator, second  stage regulator, high pressure hose with gage and a BCD inflator hose. You will need to add a second BCD inflator  hose to one of the octopus units. Air Balance Process
This Air balance System connects the tank systems together at the low pressure side. Diving on Dual Tanks
Start with the Octopus unit with  the second BCD inflator hose. This Octopus unit is please on the tank that is  on the same side of the BCD inflator value. One of the BCD inflator hose is  attached to the inflator value. The other BCD hose is connected to the short  side of the Transfer Value. The high press hose and gage is routed to the right  hand side of the diver. The second stage regulator is also routed to the right  hand side of the diver. The second Octopus is placed on the adjacent tank and the  BCD hose is routed to the Transfer Value and connected.

FAQ
Q. Do I need to buy first- and second-stage regulators from the same company?
Q. Do my regulators need regular maintenance?
Scuba regulators we recommend
 Experienced divers will often mix and match equipment. However, if you're relatively new to scuba diving, getting both from the same source guarantees they'll work well together — something that can be a challenge if you buy separately. Q. Do my regulators need regular maintenance? A. Yes. The manufacturer will give instructions, including a recommended service interval (dive centers will usually do this for you). The most important task is to rinse your regulators in clean, fresh water after every dive. Although designed to work in salt water, it will still corrode them if not washed out. Leave to dry naturally, out of the sun. Scuba regulators we recommend

Scuba Diving Regulators Buying Guide
The keystone of the diving experience, the scuba regulator is the interface between man and tank that supplies the diver with air at ambient pressure. The first stage of a regulator attaches directly to the tank, reducing the pressure of the air leaving the tank by a preset amount. The second stage reduces the pressure yet again, bringing it down to ambient pressure, where you'll be able to breathe air comfortably. There are a number of options for both stages, including ports for pressure gauges, low pressure inflator hoses, and dry suit hoses. You can also choose whether or not the first stage of the regulator is balanced or unbalanced - the advantage of a balanced first stage is that it allows you to breathe just as easily at low tank pressures, or at depths of up to 90ft. With multiple options for adjustment knobs, air flow dials, and the like, you'll always be able to alter the regulator's flow rate to compensate for any changes in depth.

When learning about diving, you are shown the diving equipment and how to use it. But often left unexplained is exactly how each component in your dive kit works. This knowledge comes in handy when you are looking to buy your own dive gear since they can be quite expensive. After all, you’d always want to choose the right one that will suit your needs. And in this article, we aim to help you understand one of the most important pieces of your scuba equipment —your scuba regulator. What is a Scuba Diving Regulator? A scuba regulator is literally the lifeline between you and your air source while diving. It is the most important and key piece of any diver’s equipment as it connects to the gas cylinder (or tank) and allows the diver to breathe air from the tank. Together, the regulator and tank make up a self-contained underwater breathing apparatus (SCUBA), which is what makes breathing possible underwater.

FAQ – Frequently asked questions about dive regulators

Dive instructor & Author
Thomas is a dive geek. Loves the geer, tech and guides. A diver’s regulator is their best underwater friend—besides their buddy, of course! Without our regs, we’d be limited to the surface and breath-hold dives. Regulators are what allow us to breathe from high-pressure, compressed air at depth. To do this, regulators take the high pressure from the tank and then regulate it so that we can breathe gas at ambient pressure–the water pressure we are surrounded by at any given time on the dive. Most scuba regulators are sold slightly differently to what you may have encountered with rental equipment. Instead of buying a complete set in one go, the first stage and the primary second stage are sold together. You then purchase the alternative second stage (or octopus) and any gauges separately. Here, we’ll be going over the best scuba regulators.

Types of diving regulators
Gas pressure regulators are used for several applications in the supply and handling of breathing gases for diving. Pressure reducing regulators are used to reduce gas pressure for supply to the diver in demand and free-flow open circuit breathing apparatus, in rebreather equipment, and in gas blending procedures. Back-pressure regulators are used in the exhaust systems of the built-in breathing systems of diving chambers, and in the recovery of used helium based breathing gas for recycling. Some of these regulators must work underwater, others in the more forgiving conditions of the surface support area. All must work consistently and reliably, but some are parts of safety-critical life-support systems, where a single point of failure must not put lives at risk. Open-circuit scuba regulators

A 1964 scuba cylinder valve with reserve, commonly known as a "type J" valve. The inlet is threaded 3/4"-14 NPSM and the outlet is a standard CGA 850 yoke type. The first-stage of the scuba regulator may be connected to the cylinder valve by one of two standard types of fittings. The CGA 850 connector, also known as an international connector, which uses a yoke clamp, or a DIN screw fitting to connect it to the valve of the diving cylinder.

What do steep pressure gradients show/indicate in weather patterns? A scuba regulator works in two stages. Cleverly named first stage and second stage. First stage attaches to your tank and regulates pressure of the Tank which ranges from 3200–500 psi down to 200 psi. Your second and your buddy/safe second, regulates from 200 psi to just above ambient pressure from your primary go to your mouth.

Advice on choosing the right scuba regulator for you. Choosing a scuba dicing regulator can seem a daunting task. First comes the shock that the price of the typical regulator set does not include the octopus, gauges and BCD inflator hose that was always included in the rented and school equipment you have been using. A typical regulator set comprises the first stage regulator with one second stage regulator. However, modern regulators all come up to a very high minimum standard so whichever you decide to purchase, you are unlikely to be disappointed. For a large range of Regulator and Octopus options for all conditions visit the Regulators section in the The Scuba Doctor Online Dive Shop. For a large range of Instrument options for all conditions visit the Instruments section in the The Scuba Doctor Online Dive Shop. General Scuba Regulator Guidelines
The basic rule of thumb with selecting a diving regulator is to go for the most expensive you can afford that is most suited to the diving you will be doing. The more you spend the easier it will be to breathe from.

 Tested vigorously by Scuba Lab, many of these regulators received perfect scores in their categories. Quality regulators from world-famous brands can be found here, brands like Mares, IST, Aeris, and Oceanic. With features like 360 degree first stage swivel, and heat exchangers to fight freeze-ups, you won't find yourself wanting with these scuba regulators. DIN Scuba Regulators
A DIN regulator can be attached only to a DIN valve, which is incompatible with standard Yoke regulators and valves. The best way to check if your valve requires a DIN regulator is to check where the two connect - if they must be screwed together, there is a good chance you have a DIN valve. If a metal brace has to go over the tank valve, and the brace screwed down to clamp the first stage, then you have a Yoke valve. DIN valve/regulator connections are more streamlined than Yoke connections, requiring less outside hardware to attach. A DIN valve and regulator can also handle higher pressures when configured correctly, and may be the ideal solution for technical and professional divers. Scuba Regulator Accessories
Find items to protect, maintain, and repair your regulator right here. Padded regulator bags will keep your most important components safe during travel, serving as a low-cost insurance policy for a high-cost piece of gear.

 Never use damaged or defective equipment. In fact, it's best not to use a regulator that you do not know the history of - it may have been misused or repaired by an unauthorized person. Refer any problems or defects to the manufacturer for recommendations and authorized repair. Regulator Tips: Opening a Regulator - Stand on the valve side of the cylinder at arms length so you do not have to reach in front of the regulator face. Turn your head away from the regulator and open the valve, turning counter clockwise, to blow out dust and debris, and then reclose the valve. Changing a Regulator - Close the valve and drain the regulator by backing out the adjusting screw. Disconnect the regulator, making sure not to touch the nut and gland areas. Connect the regulator to the new cylinder. Closing a Regulator - Turn the valve clockwise to close the valve.

 A diaphragm first stage has many moving parts but is much simpler to manufacturer, offering a lower initial purchase cost but lower performance (not generally noticeable within recreational sports diving limits). However, diaphragm regulators tend to offer more protection in colder water against free flow. Overbalanced Regulators
An over-balanced first stage achieves unprecedented performance by increasing your air supply the deeper you go. Scuba Regulator Ports
Most regulators first stage will have 1 high pressure port (7/16" thread) and 4 low pressure ports (3/8" thread). Having differing port sizes avoids any error in fitting as a high pressure hose is too big to fit in a low pressure port and vice versa. Higher specification first stages may have an additional high pressure port which is ideal when you have computerised gauges and require an analogue back up gauge in case of battery failure. Some first stages feature a special low pressure port that is designed for use with the primary second stage as the air flow to that port is higher than the others. Nitrox Compatible Regulators
Unless stated by the manufacturer, regulators are not suitable for use with elevated oxygen content mixes. Most leading manufacturers now make their entire range suitable for use with nitrox (EANx) up to 40%. Above this level you need to opt for specially cleaned regulators such as some of the Apeks Nitrox range of regulators.

Best Scuba Diving Regulators 2021 – Buyer’s Guide
December 1, 2020 By Brian Smith 1 Comment
Are you planning to take your love for scuba diving a level up? It all starts with getting your own kit because it gives you the comfort of diving when you want? To start with, scuba diving regulators are an integral part of the kit. It is an important tool as it regulates the pressure and delivers the pressurized breathing gas to diver by reducing it to ambient pressure. It is the main connecting link for the scuba equipment and diving without this is not possible. There is just one minor problem while contemplating on the idea of purchasing one. It is a daunting task to find a good product out of the lot. Here, we have created a list of best scuba diving regulators after personally testing each of it individually. I hope, this guide definitely helps you make a better purchase. Best Scuba Diving Regulators 2019

These terms refer to the way the first stage of your regulator reduces tank pressure to an intermediate pressure. Piston regulators have a very good flow rate. They generally have only one moving part (the piston) which can make them quite expensive since the machining to make the body must be exact. Piston first stages tend to be more expensive to buy as they have to be manufactured more precisely, but having fewer moving parts makes them even more reliable and less expensive to service. Most deep divers will insist on a piston first stage. A diaphragm first stage has many moving parts but is much simpler to manufacturer, offering a lower initial purchase cost but lower performance (not generally noticeable within recreational sports diving limits). However, diaphragm regulators tend to offer more protection in colder water against free flow. Overbalanced Regulators
An over-balanced first stage achieves unprecedented performance by increasing your air supply the deeper you go. Scuba Regulator Ports
Most regulators first stage will have 1 high pressure port (7/16" thread) and 4 low pressure ports (3/8" thread). Having differing port sizes avoids any error in fitting as a high pressure hose is too big to fit in a low pressure port and vice versa.

 While regulators may be more familiar, scuba valves also make up an integral part of every diver’s underwater breathing equipment as it opens and closes the tank. It’s also the part that connects to your regulator, so it’s crucial for every diver to be familiar with both. Below, we’ll explain the main components, attachment methods, and the most common styles of scuba tank valves that are available on the market for today’s deep-sea divers. Main Components of Scuba Tank Valves
Thermo by XS Scuba Din/Yoke Valve Pro 2400 PSI EANX
While there are several styles of scuba valves available, they essentially have the following components: Knob
The knob is what opens and closes the valves, allowing you to control air flow. Turning the knob left (counterclockwise) would open the valve while turning it right (clockwise) would close it. O-Ring
Scuba valves typically have an O-ring that helps create a secure seal between the valve and the regulator. However, it can sometimes be on the regulator itself, depending on the connection or attachment method used (more on this below). Burst Disk
This thin copper disk is more of a safety feature that is designed to rupture once the tank’s internal pressure reaches a certain level, thus helping divers avoid serious bodily injuries. Snorkel
The valve snorkel is not what you wear but a tube that extends from the bottom of the valve and stops debris from flowing through it when the tank is inverted.

Scuba Regulator
The regulator set consists of a 1st stage, which is mounted on the tank valve. Then there are two regulators in the 2nd stage: a pressure gauge and a low-pressure inflator hose that is attached to the BCD inflator. The regulators have a primary and an alternate air source. The alternate air source is for you or your buddy in an emergency or a back up is needed. A modern regulator is a demand valve regulator, which means it give you air when you want it. When you breathe in, air flows from the tank through the 1st stage and to the 2nd stage supplying air to you. The pressure gauge shows how much air is in the tank and usually has a caution area that warns you when the air is getting low.

THIS RESPIRATOR IS INTENDED TO BE USED ONLY IN CONJUNCTION WITH AN ORGANIZED RESPIRA- TORY PROTECTION PROGRAM WHICH COMPLIES WITH THE REQUIREMENTS OF "PRACTICES FOR RESPIRATORY PROTECTION," Z88.2 AVAILABLE FROM AMERICAN NATIONAL STANDARDS INSTITUTE INC., 1430 BROADWAY, NEW YORK, N.Y., 10018, OR THE REQUIREMENTS OF OSHA SAFETY AND HEALTH STANDARD 29 CFR 1910 PARAGRAPH 134 AVAILABLE FROM THE U. S. DEPARTMENT OF LABOR, OC- CUPATIONAL SAFETY AND HEALTH ADMINISTRATION, OR OTHER PERTINENT NATIONALLY RECOGNIZED STANDARDS, SUCH AS  THOSE PROMULGATED BY THE US COAST GUARD OR THE DEPARTMENT OF DEFENSE. 5 The regulator utilized by the SCOTT SCBA is a pressure-demand breathing regulator mounted directly to the facepiece. The regula- tor may be removed from the facepiece by operating a spring loaded thumb latch, rotating the regulator 90 degrees and lifting it from the facepiece. The breathing regulator is equipped with an air saver/don- ning switch which can be activated by depressing the rubber covered switch. Activation of the air saver/donning switch will prevent the rapid loss of air supply when the system is turned on prior to don- ning the facepiece, if the facepiece is removed from the face or the regulator is removed from the facepiece while the cylinder valve is open. The regulator is also equipped with a red purge knob. The purge knob is an emergency control which allows air to flow into the facepiece without breathing

 Turn your head away from the regulator and open the valve, turning counter clockwise, to blow out dust and debris, and then reclose the valve. Changing a Regulator - Close the valve and drain the regulator by backing out the adjusting screw. Disconnect the regulator, making sure not to touch the nut and gland areas. Connect the regulator to the new cylinder. Closing a Regulator - Turn the valve clockwise to close the valve. Drain the regulator by turning (opening) the adjusting crew to release any gas. Reclose the adjusting screw. Recommendation: To provide easier access and additional safety, purchase wall-mounted regulators which connect to the supply cylinder by hose. This will reduce the handling of the regulator and reduce the likelihood of damage.

 One hand holds your mask while the other holds your regulator. So far so good. Time to make the entry. You enter the water backward, reorient yourself and bob to the surface. While thinking about what you need to do next, you forget to move out of the way for your buddy to enter the water, and you get a warning from the divemaster. After moving back from the boat, you place the regulator mouthpiece in the water. You place it face-down to prevent free-flow. You then replace the regulator mouthpiece in your mouth and exhale to clear it. You carefully inhale to make sure it is completely cleared. Advertisement
You adjust your buoyancy compensator (BC) to make yourself more buoyant while you wait for the others to enter the water.

 You want to use a pure Argon gas or mixed Argon gas such as an Argon-Helium mixture. Remove the plastic protective cap. Shift the valve body by quickly opening and closing the valve to clean any debris out of the threaded valve body. Screw the regulator on, then screw the nut tight while simultaneously twisting the regulator until it is seated in the valve. Tighten the regulator using a spanner, making sure that the pressure knob is backed off counter-clockwise. Put on the gas hose and flowmeter, then turn on the cylinder valve. Make sure to turn on the cylinder valve gently and in small increments. Usually a quarter-turn revolution is enough. Finally, check for any leaks by listening for a wheezing sound or using an aerosol leak detector spray. Set the gas flow rate by adjusting the cylinder regulator.

 Extra padding at the back of the neck. Stylish design. What we don’t like: If diving in cold water, there may not be enough releasable weight (16 lb / 7.25 kg). No right shoulder exhaust valve. Zippered weight pockets. Would be nice to be able to pick your color! See more BCD's
Scuba Regulator
The regulator set consists of a 1st stage, which is mounted on the tank valve. Then there are two regulators in the 2nd stage: a pressure gauge and a low-pressure inflator hose that is attached to the BCD inflator.

 This was why when I began my PADI certification, one of the first things that I did was to get my own gear. It was only then that I realized just how difficult to find the best scuba regulator. Being older and wiser, however, I now have the experience to help out others in this situation. Best Scuba Regulators

Scubapro is all about improving on what is great so that they can achieve perfection. This is why this is the fifth edition for this model. Now, this is not to say that the MK25/2600 is perfect. I do feel, however, that it is pretty close to that. Let me explain why…
I really liked the fact that it was easy to breathe with this regulator. This is due to several components including the extremely stable intermediate pressure offered by the MK25 first stage as well as the air performance of the S600 second stage.

 Many of the more expensive options are now being built as “BCD for life”. These options typically are built in a way where everything is replaceable. If you lose a weight pocket or break a strap you can simply replace that individual piece. Scuba Regulator Cost
The scuba diving regulator consists of two parts. The first stage connects directly to the scuba tank. The second stage connects to the first stage and is the piece you put into your mouth and breathe out of. The type of regulator that you choose will depend on the conditions you dive in. For example if you will be doing cold water diving where there is a chance of freezing you would want a diaphragm design versus a piston design. In most cases you will purchase the first and second stage as a combination pack. Another major difference is balanced versus unbalanced regulators.

 Put air in your BCD. Put enough air into your buoyancy control device (BCD) to bring you to the surface after you’ve jumped in. This allows you to come together with your buddy before you descend on your dive as a buddy pair. Put your regulator in your mouth. Breathe in as a final check that your regulator is working and your air is switched on. Protect your equipment. Put one hand over your mask and regulator to prevent them from dislodging on entry. Put your other arm around your other equipment to avoid these from hitting you as you enter the water. Wait for the all-clear from the skipper. Before entering the water, always wait for the boat skipper to give you the all clear.

 Aside from protecting your fingers and palms, these gloves help keep your hands warm underwater. Scuba Tank
A scuba tank or diving cylinder is obviously another piece of equipment that you’re going to need when you go diving. It is a component of your breathing apparatus and serves the purpose of allowing you to store and transport large volumes of simple compressed air or specialized gas mixtures such as Nitrox. Most tanks have a maximum pressure rating of around 2000 to 3500 psi and are commonly made from either steel or aluminum. You can choose to rent or buy, although if you plan to do more dives in the future, you may want to invest in your own. Regulator
The regulator makes it possible for you to breathe the air from your tank by converting the high pressure air into ambient pressure. It has something called a first stage, which connects to the tank or diving cylinder you wear on your back, and a second stage—the part of the regulator that you put in your mouth. It also has a backup second stage and gauges. When choosing a diving regulator, make sure to pick one that gives you the highest level of comfort and performance for your own needs. Depth Gauge, Submersible Pressure Gauge, & Compass
A depth gauge records the current and maximum depth reached during a dive.

 A small rush of air will escape. Quickly close the valve. Performing this task removes any dust. Make sure that you point the valve away from yourself or anyone else when you undertake this step. Next, review the regulator to see if it displays a washer. If a washer does not exist, a large amount of oxygen can be lost if you open the valve. Call the supplier of the tank if your tank does not display this important part. Slide the regulator across the stem so you align the two regular pins with the holes of the valve stem. The regulator has been seated correctly once the two pins easily slip into the holes. Tighten the pins with the regulator’s T bar.

 Put enough air into your buoyancy control device ( BCD) for positive buoyancy. This brings you to the surface when you jump in. This allows you to come together with your buddy at the surface before descending on your dive as a buddy pair. Put your regulator in your mouth. Breathe from your regulator as a final check your regulator is working and your air is switched on. Protect your equipment. Put one hand over your mask and regulator to prevent these from dislodging on entry. Put your other arm around your other equipment (your hoses, gauges and dive torch etc.) to avoid these from hitting you as you enter the water. Wait for the all-clear from the skipper.

Hi I’m Russell Bowyer
 This should be enough air to make you buoyant enough to bring you to the surface after you’ve rolled back into the water. This allows you to come together with your buddy before you descend on your dive as a buddy pair. Put your regulator in your mouth. Breathe in as a final check that your regulator is working and your air is switched on. Protect your equipment. Put one hand over your mask and regulator to prevent them from dislodging on entry. Put your other arm around your hoses, gauges and other equipment to avoid these from hitting you as you enter the water. Wait for the all-clear from the skipper. Before entering the water, always wait for the boat skipper to give you the all clear. The all-clear indicates the boat is correct placed and the boat is in neutral.

 The nylon washer goes inside the regulator CO2 inlet nut. The inlet nut then screws directly into the CO2 air tank. Use the CO2 air tank wrench, which you can leave hanging down from the regulator afterwards, to screw the two pieces together. Single-gauge regulators show just the PSI level the beer is pouring at, while dual-gauge regulators also show the amount of compressed air remaining in the tank. Step 9: Attach coupler to keg. Assuming you're using the correct keg coupler for the beer style you're pouring out, your coupler will screw in relatively easily by fitting into the grooves atop the keg. Begin with the coupler's handle in a closed position, or facing diagonally and upright. After screwing the coupler into the keg, creating a firm seal, you can then push the coupler handler downwards, so that it is lowered and facing more straight out than diagonal. Some beer should enter the vinyl beer line at this point.

 The second stage connects to the first stage and is the piece you put into your mouth and breathe out of. The type of regulator that you choose will depend on the conditions you dive in. For example if you will be doing cold water diving where there is a chance of freezing you would want a diaphragm design versus a piston design. In most cases you will purchase the first and second stage as a combination pack. Another major difference is balanced versus unbalanced regulators. A balanced regulator will provide air at a consistent rate regardless of your depth or remaining air amount. Whereas an unbalanced regulator will have a noticeable difference the deeper you go and as your tank gets closer to empty. Balanced regulators are generally more expensive. Scuba regulator costs will range between $200 to more than $2000. The majority of first and second stage setups will cost around $500-$700.

 Make sure all of your valves are in the off position. This should be apparent for your CO2 tank (else it would be leaking), however, it might be a tad more complicated for your regulator. In general -- righty tighty, lefty loosey. Clean the threads on your CO2 tank with a wet cloth. Let dry. Starting at the edge of your threads, wrap the tape around the end a few times, going in the direction of the thread. Wrapping opposite of the threads may result in the tape coming loose while tightening on the regulator. Insert the Compression ring into the Regulator Screw. Screw on the regulator by hand, then tighten using a wrench. Ask Question

 CO2 gas line tube (7) to the regulator by attaching one end of the tube into the hose barb connection on the CO2 regulator and secure the tube by using one of the two self-locking red plastic snap-on clamps (15). Use pliers or clamp crimpers to snap the clamp on as high as possible, and make sure the clamp does not impede the valve. Then remove the black rubber plug from the back of the unit and feed the remaining unused end of the tubing through the hole. 7. Connect Regulator to Cylinder
Make sure the CO2 cylinder (8) is full and closed. Then attach the CO2 regulator (6) to the cylinder by screwing the loose golden regulator nut into the cylinder valve and tightening with a wrench or pliers. Note that a fiber washer is normally required to connect a regulator to a CO2 cylinder, but a standard regulator generally includes a built-in O-ring. 8. Mount CO2 Cylinder
Now mount the CO2 cylinder holder (9) to the cabinet. Match up the holes on the holder with the screws jutting out of the back of the cabinet and slide the holder down to lock it in place.

How do you change portable oxygen tank?
Your Answer
How do you change portable oxygen tank?
 Check to be sure that the washer is in place on the inlet of the regulator. Remove white protective seal from the full oxygen tank valve. Slide the regulator over the top of the tank valve and place the two index pins into the two holes in the tank valve. Be sure that the two index pins properly fit into the holes. Turn the "T screw handle" clockwise until snug. Open the tank valve very slowly by turning the tank valve key one full turn counterclockwise. If you hear a leak: Turn the tank valve off and relieve all pressure from the regulator by turning the flow control knob to "2 or 3" and wait for the oxygen flow to stop. Turn the regulator off by turning the flow control knob to "O". While supporting the tank, loosen the "T screw handle" by turning counterclockwise several turns and then remove regulator from tank valve, taking care to prevent the oxygen tank from falling to the ground.

 Follow these steps accordingly: You start off by connecting all the components together. Follow this arrangement to get it done easily- Tighten the regulator with a spanner and attach it to the CO2 tank. Place the diffuser inside the tank, and make sure it is placed properly. Connect the diffuser and bubble counter with a CO2 resistant tubing. Attach a solenoid valve to the regulator if the solenoid is separate from the regulator
When all the parts are connected, you move to the next phase. First, slightly open the needle valve that is on your regulator. This will make sure no harm happens to your solenoid when the main valve of the bottle is released. Now you can switch on the main valve of the bottle to release CO2. If the bottle is full, the gauge would indicate 800-1000 psi.

How A Water Pressure Regulator Works
 Set up Your Plastic Sheeting and Bucket
Even though you have drained the water, some water will be trapped inside the old valve. Set up plastic sheeting underneath and behind your work area, then create a path for the water to empty into the bucket by draping the plastic sheeting into the bucket. Prep the New Valve
Since you are using the existing connections, you need to remove those from the new valve. They are the nuts on either side of the valve. Pay attention and save the O-rings that come with the new valve—you will need these, so take care not to lose them. Remove the Old Regulator
Loosen the nuts on each union with a wrench. Hold the regulator in place with a wrench while you finish unscrewing the nuts by hand, ensuring it doesn't twist and bend the plumbing or compromise the threads. Remove the old regulator carefully - this is the step where the water will come out, and you'll be glad you set up that bucket. Install the New Regulator
Seat the O-rings and install the new regulator. The valve is directional and must be installed right side up.
