Single Pilot Operated Check Valve With Manual Shut-Off
Use and operation:
Pilot check valves are used to block the actuator in both directions. Flow is free in one direction and blocked in the reverse direction until pilot pressure is applied. These valves are very safe, that’s why they are ideal to be assembled on crane hydraulic cylinders. The shut-off system enables to exclude any risk caused by possible manoeuvring errors.
Applications:
Connect V1 and V2 to the pressure flow, C1 to the free flow side of the actuator and C2 to the actuator’s side you want the flow to be blocked.
