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.

Materials and Features

• Body: zinc-plated steel
• Internal Parts: hardened and ground steel
• Seals: BUNA N standard
• Poppet Type:  any leakage

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.
