CKCBXCN - Check Valve Cartridge

Pilot-to-open check valve with a standard pilot. It allows free flow from the valves (port 2) to the load (port 1)and blocks flow in the opposite direction. Pressure at the pilot (port 3) will open the valve from port 1 to port 2. The pilot pressure needed at port 3 to open the valve is directly proportional to the load pressure at port 1. Pressure at port 2 directly opposes pilot pressure. The valve provides hose break protection, preventing loads from drifting and positively locking pressurized loads.
