GPOC2 Pilot-To-Open Check Valve
| Operation | P.O. check allows free flow from the valve port to the cylinder port and prevents reverse flow with no pilot pressure. With adequate pilot pressure applied to the pilot port, the pilot piston unseats the check poppet allowing reverse flow. Minimum pilot pressure required to open this valve is found by dividing the cylinder pressure by the valve's pilot ratio. (ex.. 1500 psi @ cylinder / (3:1) = 500 psi minimum pilot pressure required.) |
| Type | Poppet type check valve with an internal pilot piston. |
