Energy saving silencing check valve is a pioneering and exclusive patented product designed by our company based on Hydromechanics, Noise Control, Formation and Elimination of Cavitation theories.

Application: It is well proved by its long-term service in the water supply companies, fire protection systems and power plants that it can prevent reverse flow to protect pump and

electrical motors from flow reversal damage and it can also reduce water hammer to protect the piping facilities.

A、Streamline valve internal vault and 100% flow capacity design with less blind bends, corners, and sharp protrusion for reducing flow resistance.

B、The front and back of valve disc is tapered design to make flow resistance greatly decrease and lower down the noise as well caused by vortex flow.

C、Short closing distance travelled by the valve disc, only 1/4 DN, reducing the closing time and decreasing the water hammer

D、Using spring to accelerate closing time of the valve disc, and decreasing the water hammer

E、Hollow and thin shell structure of the valve disc, reducing the valve disc’s inertia, not only provides quick action when the valve disc is closing, but also lowers down the impacted noise as well.

F、Installed in vertical, horizontal, slanted, and any other angle.

G、Compact structure, few parts, small volume, light weight, and good appearance.

H、Both inner and outer surfaces of the valve body are electro-statically coated with epoxy resin powder which is environmentally friendly and non-toxic to ensure strong corrosion resistance capacity
