This unit is a screw in, cartridge type, guided poppet, hydraulic pilot operated check valve, for use as a blocking or load holding device for high pressure applications.

POCX allows free flow from port 2 to port 1 and blocks flow from port 1 to port 2 or holding a load. Flow will be allowed from port 1 to port 2 when pressure is applied to pilot port “P”. This pilot operated check valve has a 3 to 1 pilot ratio, meaning that it takes at least one third of the load pressure held at port 1 that is required at pilot port “P” to open the valve. It is recommended to use an orifice to dampen the pilot signal when used with an on/off (hard shifting) valve.
