H42 Vertical lift flanged check valve

Flange check valveis to rely on the flow of the medium itself and automatically open, close disc, used to prevent the medium backflow valve, also known as the check valve, one-way valve, reverse flow valve, and back pressure valve.Check valve belongs to a kind of automatic valve, its main function is to prevent the backflow of media, prevent the reversal of pump and drive motor, as well as the release of container media. Check valves can also be used in piping where pressure may rise above system pressure to supply an auxiliary system.Check valves can be divided into swing check valves (rotating according to the center of gravity) and lifting check valves (moving along the axis).

The purpose of this type of valve is to allow the medium to flow in only one direction and to stop the flow in that direction.Normally the valve works automatically and the disc opens under pressure from a flow of fluid in one direction.Flow in the opposite direction, by the fluid pressure and disc self - coincidence disc on the seat, thereby cutting off the flow.
