Cast iron valves for water treatment systems

Clamp check valve

This valve consists of valve body, valve disc, valve stem, spring and other parts, and is connected by clamps. Due to the short closing stroke of the valve disc and the spring loading, water hammer phenomenon can be significantly reduced. Mainly applicable to the water supply and drainage pipelines and other non corrosive medium pipelines in cities, industries, and high-rise buildings, to prevent one-way opening and closing of medium backflow.

Product Message

Product characteristics

1. Thin and lightweight design, short closing stroke of valve disc, spring action can accelerate the closing effect, reducing water hammer and water hammer sound.

2. The distance between the faces is shorter than that of a general check valve, making it the most convenient for places with limited installation space.

3. Small size, light weight, compact structure, and easy maintenance.

4. Can be installed horizontally or vertically on pipelines. When installed on a horizontal pipeline, the valve axis should be perpendicular to the water surface. When installed on a vertical pipeline, the fluid direction should be from bottom to top.
