USE AND OPERATION:
These valves are used to block the cylinder in one direction. The flow is free in one direction and blocked in the reverse direction until pilot pressure is applied. Thanks to its high pilot ratio and to a time-lag locking device,it.s suitable to avoid vibrations in circuits with heavy loads.

APPLICATIONS:
Connect V to the pressure flow, C to the actuator* s side you want the flow to be blocked and Pil to the pilot line.
