Also known as FIV or cat AIDS, feline immunodeficiency virus is an infectious disease caused by a retrovirus belonging to the lentivirus family. It is in the same family as the feline leukemia virus (FeLV), and is similar to the HIV virus in humans. FIV infects both domesticated cats, lions, tigers, pumas and cheetahs.
This map only incorporates the wide-open throttle condition, but adding a third independent axis of throttle position can create a 3D performance map; it is noted that throttling directly affects efficiency via an inverse proportion, and maximum efficiency and minimum BSFC is realized at 100% throttle.
globe valves are commonly used as an on off valve but they may be used for throttling systems the gradual change in spacing between the disk and seat ring gives the globe valve good throttling abilityn globe valves flow rate is determined by the lift of the valve plug from the seat manual globe valves can have equal percentage linear or quick opening flow since flow characteristics determine the flow rate the operator can roughly determine the flow rate by the linear position of the manual handwheel
