Product Description
1. Product description
Check valve are self operated type, automatically open or closed by flow service, it's adopted for prevent the service flow in reverse direction. The function of the check valve is allow service flow in one direction, and prevent the service in reverse direction. And generally the valves are operated automatically, the valve open by service pressure of one direction; when the service flow in reverse direction, then the flow service pressure press the disc to the seat, and shut off the flow.2.

(3), sealing surface is not easy to wear, abrasion, good sealing performance, long life.
(4), Simple in shape, short face-to-face length, good technic in producing, and widely applied
5. Working principle of forged steel Lift check valve:
The disc of the lift check valve is on the upside of seat sealing surface. The disc can be up and down freely, the other parts of valve are the same as globe valve, the flow pressure press the disc from the seat sealing surface, then the disc is lifted, when the flow service flow in reverse directio, the disc will go down to seat sealing surface, and shut off the flow. The disc can be full metal depends on the application, also we can insert the rubber gasket or ruDTer ring to the disc depends on the application. The service flow through the lift check, the bore are as narrow as globe valve's. so the pressure loss of lift check are big than swing check, and the flux of swing check limited little.
Lift check valve can only installed on horizontal pipeline, ball can be the alternative of disc for high pressure and small size check valve;You need to consult more detailed product information
