H47 Check Valve

The H47 check valve designed by Dazhong Valve Group adopts a sloping plate structure to achieve no vibration, no noise, stable operation, quiet hotel and residential environment, and energy saving effect. The partial backflow water is leaked into the system by means of delayed closing. The shut-off seal is made of nitrile rubber. The valve is mainly composed of a valve body, a valve disc, a buffer device and a micro-control valve.

The HH47 type micro-resistance, slow-closing, noise-absorbing check valve produced by our group is mainly used in industrial, urban water supply and drainage pipelines, and at the exit of high-rise residences, high-end hotels, and pressurized water pumps.
In the design, the requirements of the use environment are fully considered, and the inclined plate structure is adopted to achieve no vibration, no noise, stable operation, ensure the quiet environment of hotels and residences, and have the effect of energy saving.
The local backflow water is released into the system by means of delayed closing, which greatly reduces the water pressure impulse of backflow when the pump is stopped, and eliminates the generation of destructive water hammer peaks. The shutoff seal is made of nitrile rubber. It has the characteristics of good sealing performance, shock absorption and wear resistance, long service life and convenient maintenance.
HH47 type micro-resistance slow-closing muffler check valve is mainly used for industrial water supply and drainage, pump outlet of sewage treatment plant to prevent backflow of medium in the pipe network.
Automatically eliminate damaging water hammer, thus ensuring that pumps and piping are not damaged.
The valve is mainly composed of valve body, valve disc, buffer device and micro-control valve. The product has novel structure, small volume, low fluid resistance, stable operation, reliable sealing, erosion resistance, wear resistance, buffering With good performance and other characteristics, it is the best product for industrial water and urban sewage.
