The function of the valve is to prevent the flow in the opposite direction and only allow the medium to flow in one direction. Usually, the 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 to cut off the flow. It is not suitable for medium with solid particles and high viscosity.

Product Features

1. Short shutoff stroke of valve core, combined with the closed design of spring speed, can effectively reduce the influence of water hammer.

2. Before the water hammer strikes, the valve has been closed to achieve the mute effect.

3. Full flow design, water loss is very low.

4. Because the use of both ends of the disc guide design, can be applied to any direction of installation.
