Wafer lift check valve

Short Description:

The main function of wafer lift check valve is that the water hammer pressure is very small, the valve disc stroke is short, the valve disc is light, it has the spring auxiliary closing and the valve closing speed is very fast. The structure length is very short, the volume is very small, the weight is very light, it brings great convenience for the valve installation, handling, storage and pipeline layout, and can save a lot of materials and reduce the cost.

Wafer lift check valve is to rely on the flow of media itself and automatically open and close the valve disc, used to prevent the reverse flow of medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. Check valve is a kind of automatic valve. Its main function is to prevent the reverse flow of medium, reverse rotation of pump and drive motor, and discharge of container medium. The check valve can also be used to supply the auxiliary system in which the pressure may rise above the system pressure. Check valve can be divided into swing check valve (rotating according to the center of gravity) and lifting check valve (moving along the axis). This kind of valve should be installed horizontally in the pipeline.
