The HH44ZX check valve designed by Dazhong Valve Group is used on water supply and drainage pipelines and installed at the pump outlet to prevent the backflow of the medium and eliminate the destructive water hammer, and can effectively reduce the pressure of the valve closing water hammer, which can protect the pipeline Safe and reliable operation of the network. It has the advantages of light valve disc, large opening, power saving, small fluid resistance, novel design of water hammer elimination mechanism, stable and reliable sealing performance, wear resistance and long service life.

Equipped with a counterweight device. When the valve flap swings, the resistance to water flow is small, and the valve opening force is only one-fifth of the original swing type, which is an energy-saving product.
A damping device is provided in the rear stroke of the valve disc closing, and the damping time is adjustable to prevent the generation of destructive water hammer.
The rubber-coated valve disc design, reliable sealing, anti-corrosion, vibration and wear resistance, long service life, stable operation and low noise.
