Aircraft
We were on the approach and after normal gear extension we got a R HYD ISO VLV caution light; and subsequent loss of the number two hydraulic quantity. We executed a go around and completed the checklist's; declared an emergency with Approach and then accepted vectors back to the ILS approach and made a normal landing.
DHC8 First Officer reports loss of the right hydraulic system during approach. A go around is initiated; the QRH is consulted; an emergency is declared and a normal landing ensues.
