Over Pressure Valve
The Blue Orb Over Pressure Valve is for any 1st stage that doesn't have a 2nd stage to relieve excessive pressure if the 1st stage fails. Primarily used for argon suit inflation cylinders that don't have a 2nd stage, you need an OPV to prevent excess pressure building up in the 1st stage and hose leading to your suit that could cause damage or uncontrolled inflation.
Simple design screws into a 3/8" UNF LP Port and will purge any gas if the interstage pressure grows over 200psi / ˜14bar
