Micro-Stop Slow Closing Silent Check Valve

Micro-Stop Slow Closing Silent Check Valve

The silent check valve is mainly used for industrial water supply and drainage, sewage treatment plant pump outlet, urban water supply and drainage pipeline and high-rise residential, high-end hotels, pressure pump outlet, to prevent the official website medium countercurrent.The design fully considered the requirements of the environment, the use of slanted plate structure, to achieve no vibration, no noise, smooth operation, ensure the hotel, the residential environment is quiet, and has the effect of energy saving.The local backflow water is discharged into the system by delaying the closure, which greatly reduces the hydraulic impulse of backflow after stopping the pump and eliminates the generation of destructive water hammer peak value, thus ensuring that the pump and pipeline are not damaged.Butadiene nitrile rubber (NBR) is used for closure sealing, which has the characteristics of good sealing performance, shock absorption and wear resistance, long service life, easy maintenance, etc. It is the best product for industrial water and urban sewage.
