Lift Check Valves has a disc that lifts up off its seat by higher inlet pressure. When the inlet pressure drops, the disc is closed before the back-flow reaches to the valve, enabling non-slam & drip tight closure.
It has a relatively short valve disc travel resulting in an immediate valve disc closing on no flow conditions, minimizing water hammer and surge conditions.
Lift Check Valve has a center-guided, spring loaded valve disc with a resilient seal, acting over a bronze or stainless steel removable valve seat.
It can be furnished with valve position indicator and electrical limit switches and can be serviced without being removed from the pipeline.
