E-PC08-30 PILOT OPERATED CHECK VALVE
The E-PC08-30 is a screw-in, cartridge style, pilot operated, hydraulic check valve used for blocking or load holding circuits.
E-PC08-30 allows free flow from port 2 to 3, while normally blocking flow from port 3 to 2. Flow will be allowed from port 3 to 2 when pressure is applied at port 1. The pilot ratio of the check valve is 3:1, which means that the pressure at port 1 should be at least 1/3 of the load pressure at port 3 before the valve can be opened. Under static or no load conditions, the spring pressure ensures that the valve port is closed. Hydraulic piston with seal is available.
