This double pilot operated check valve is designed to hold hydraulic cylinders and prevent them from drifting down while your directional control valve is in the neutral position. At rest the check valves remain seated, blocking flow from entering and exiting the cylinder and locking the cylinder in place. Flow Rating: 11 GPM, Pressure Rating: 5000 PSI, Pilot Ratio: 4:1, Port Size: ½” NPT Thread Carbon Steel body with black oxide finish ; Hardened, precision ground parts for durability When pressure is applied to either port, the check valve will open allowing free flow from the inlet to the actuator port across the check valve.
