GPCC17 Pilot-To-Close Check Valve

Operation	Pilot-to-close check allows free flow from the inlet port to the outlet port and blocks flow in the reverse direction. With adequate pilot pressure applied to the pilot port, the pilot piston seats the check poppet and shuts off flow. Minimum pilot pressure required to close this valve is found by dividing the inlet pressure by the valve's pilot ratio. (ex. 1800 psi @ inlet / (1.8:1) = 1000 psi minimum pilot pressure required.)
Type	Poppet type check valve with an internal pilot piston.
Material	Precision ground & honed, hardened steel parts.  Buna-N seals standard.  Zinc plated.
Pressure	Valve rated to 5,000 psi maximum. 3,000 psi maximum in aluminum block.
Flow	80 gpm nominal
Leakage	5 drops per minute
Fluid	General hydraulic fluid
Cavity	G-17A        [See Detail]
