What's Lift non-return valve ?

Lift non-return valve is designed to prevent the reversal of flow in a piping system.it's commonly used in piping systems in which globe valves are being used as a flow control valve. They have similar seating arrangements as globe valves.Lift check valves are suitable for installation in horizontal or vertical lines with upward flow.

A  Lift non-return valve is a valve which prevents the suction line from running empty, e. g. after the pump has been stopped. Spring-loaded cast steel 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.
