Lift Check Valve

Lift check valves can be divided into horizontal and vertical types. Horizontal lift check valves should be selected for horizontal installation, while vertical check valves should be selected for vertical installation. Lift check valve is an automatic valve that closes or opens the valve by the weight of the valve disc and the pressure of the pipeline in front of the valve. There are also lift check valves with springs installed behind the valve disc. The function of a lift check valve in pipelines is to prevent medium backflow and protect the safety of pipeline equipment in front of the valve. It can also be used to automatically supply auxiliary systems where the pressure may rise above the system pressure. The structural design of the lift check valve produced by Shanghai Meiyanyi Pump Valve enables it to pass smoothly during normal medium flow, but can effectively seal and prevent medium backflow when the medium flows in the opposite direction.
