Pilot check valves with integrated manual shut-off 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. Due to the high safety of these valves they are particularly suitable for fitting onto the stabiliser cylinders: closing of the manual shut-off valve, after the lowering of the stabiliser legs, would prevent any potential accidental movements.
