Ductile Iron Lift Check Valve Flanged End PN10 PN16 Pressure

Ductile Iron Lift Check Valve Flanged End

Ductile Iron Lift Check Valve

1. PRODUCT PROFILE

The 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.

The seat ring is of a barrel-type design of heavy uniform cross-section. It is normally screwed in and seal welded. The flow opening is full port size.
