Stainless Steel Material ANSI API Standards Flanged Swing Check Valve

Introduction 

The stainless steel swing check valve can also be used on the pipeline to supply the auxiliary system in which the pressure may rise above the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

Check valve the function of this type of valve is to allow the medium to flow in only one direction and prevent the flow in the opposite direction. Usually, this valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc act on the valve seat, so as to cut off the flow
