The valve is composed of valve body, disc, stem, spring and other parts, which are connected by clamp. Due to the short closing stroke of thedisc and the spring loading, the water hammer phenomenon can be significantly reduced. It is mainly applicable to the water supply and dra-inage pipe network of urban, industrial and high-rise buildings and other non corrosive medium pipes to prevent the unidirectional opening and closing of medium reverse flow.

Product Features

1. Thin and lightweight design, short disc closing stroke, spring function can accelerate closing effect, reduce water hammer and water hammer sound.

2. The distance between the surfaces is shorter than that of the general non-return valve,which is the most convenient for places with limited installation space.

3. Small volume, light weight, compact structure, easy maintenance.

4. It can be installed on the pipeline horizontally or vertically. When it is installed on the horizontal pipeline, the valve axis shall be vertical tothe water surface. When it is installed on the vertical pipeline, the direction of the fluid shall be from the bottom to the top.
