Features
Provides hose break protection, prevents loads from drifting and positively locks pressurized loads.
Standard unsealed pilot allows air trapped in the pilot line to be purged from the circuit.
Extremely low leakage. The seat and poppet are heat treated for long life. If the load drifts due to the valve, the seat has probably been damaged by contamination and the valve should be replaced.
Optional external porting out of the hex end of the cartridge is available for external piloting. In this configuration, port 3 is blocked. See Control options E, and P.
Pilot-to-open check cartridges are locking valves, not motion control valves. For motion control applications, use counterbalance valves.
