First, DHH44X micro-resistance slow-closing silencer check valve product overview

  The DHH44X/H-10/16 micro-resistance slow-closing noise-reducing check valve produced by our factory is mainly used in the outlets of industrial and urban water supply and drainage pipes and high-rise residential buildings, high-grade hotels and pressurized water pumps. The design fully considers the requirements of the use environment, adopts the sloping plate structure, achieves no vibration, no hum and stable operation, ensures the quiet environment of the hotel and the residence, and has the effect of energy saving. The partial backflow water is discharged into the system by means of delaying the closing, thereby greatly reducing the water pressure impulse of stopping the pump backflow, eliminating the generation of destructive water hammer peaks, using the nitrile rubber for the intercepting seal, and having good sealing performance and shock absorption. Wear-resistant, long service life and easy maintenance.
