Single hydraulic control check valve (flange type)

Single hydraulic control check valve (flange type)
Instructions for use:
Pilot-operated check valves are used to block cylinders in one direction, allowing fluid to flow in one direction and blocking the flow in the opposite direction until pressure is applied.
The valve can be mounted directly on the cylinder.
Application:
Connect V1 and V2 to the pressure flow, connect C1 to the free flow side of the actuator, and connect C2 to the side of the actuator that you want to block.
