Slightly retarded closed silencing check valve

DHH44H X type micro retarding check valve is mainly used in industrial, urban drainage pipes and high-rise residential buildings, senior hotels, pressurized water pump outlet. In the design, fully consider the requirements of the use of the environment, the use of inclined plate structure, to achieve no vibration, no noise, stable operation, to ensure that the hotel, the residential environment is quiet, and has the effect of energy saving. By delaying closure, the local backflow water is discharged into the system, which greatly reduces the hydraulic impulse of backflow and eliminates the destructive water hammer peak. The closure seal is made of nitrile rubber, which has the characteristics of good sealing performance, shock absorption and wear resistance, long service life and easy maintenance
