Technical parameters and characteristics
Micro Resistance Slow Closing Check Valve
The Slow Closing Check Valve is mainly used at the outlet of pressurized water pumps in industrial circulating water supply and drainage, urban water supply and drainage, high-rise buildings and hotels, to prevent water backflow and eliminate destructive water hammer to ensure the safe operation of the pipe network. In the design, the requirements of the use environment are fully considered to achieve no vibration, no noise, stable operation, ensure the quiet environment of hotels and residences, and have functions such as power saving. For the convenience of installation, there are two types of vertical installation and horizontal installation for selection.
