Hydraulic-operated sandwich check valve
This product is a pilot-operated check valve. Even with long period of pressure sustaining, one or both working ports of this valve will still have no leak due to good sealing perfromance. The pressured fluid is allowed to pass freely from A to A1 or B to B1, with reverse flow shut off. When the control valve is in the central position, the working port should be connected to fluid
piping for unload in order to ensure for proper closing of the valve core.
