What is Lift Check Valve ?

Lift Check Valve is designed to prevent the reversal of flow in a piping system. These valves are activated by the flowing material in the pipeline.The pressure of the fluid passing through the system opens the valve, while any reversal of flow will close the valve. Closure is accomplished by the weight of the check mechanism, by back pressure, by a spring, or by a combination of these means. The general types of check valves are swing, tilting-disk, piston, butterfly, and stop.

A lift check valve is a valve which prevents the suction line from running empty, e. g. after the pump has been stopped. Priming the pump prior to a re-start is therefore no longer necessary.

Spring-loaded lift check valves can be installed in the piping in almost any mounting position. Compared with swing check valves, their head losses are higher as the deflection of the flow is much more significant.

Lift check valves are preferred when applications require smaller nominal diameters.
