Cast Steel Check Valve 3

Check valves can also be used to supply pipes where the pressure may rise to an auxiliary system that exceeds the system pressure. The check valve can be divided into rotary check valve (rotation according to the center of gravity) and lifting type check valve (moving along the axis).

Check valves The effect of this type of valve is to allow only the medium to flow in one direction and to prevent the flow in the opposite direction. Usually this valve works automatically, under the action of fluid pressure flowing in one direction, the disc opens, and when the fluid flows in the opposite direction, the fluid pressure and the disc's self-contained disc Act on the seat, thus cutting off the flow.
