Ductile Iron Lift Check Valve Flanged End

Ductile Iron Lift Check Valve

1. PRODUCT PROFILE

The lift check valve is particularly adapted for high-pressure service where velocity of flow is high. In this type of check valves, the piston disc is accurately guided by long contact and a close sliding fit with the perfectly centered dash pot. The walls of the piston and dash pot are of approximately equal thickness. Large steam jackets are located outside of the dash pot and inside the piston to eliminate sticking because of differential expansion. 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.
