SINGLE PILOT OPERATED CHECK VALVES 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.
