The lift Check Valve operates by having its disk lifted off the seat to permit downstream flow. When the upstream pressure returns to a higher condition, the disk closes. It requires little maintenance, as it has only one moving part and little wear.This type of valve utilizes a flapper attached to a hinge at the top of the valve to regulate the direction of flow in the valve. Forward flow through the valve causes the flapper to move up to the open position. Backward flow in the valve pushes the flapper back against the seat, closing the valve.
