CHECK VALVEMax Pressure: 5000 PSI (345 bar)
Max Flow Rate: 35 to 235 gpm (113 to 891 l/min)
The HSC cartridge type check valve allows free flow in one direction but prevents flow in the other. It can be used to separate portions of a circuit, or with a sequence valve to provide a counterbalance valve function.
Pressure at port 1 forces the poppet off the seat and compresses the spring to allow flow to port 2. Reverse flow (from port 2) works on top of the poppet and forces it against the seat to stop flow.
The valve is constructed of steel parts, operating parts are hardened and ground as required. Cartridge is designed for easy service or field repair.
