The YQ-9000 Piston-Type Water Hammer Absorber is a device designed to eliminate water hammer shock waves caused by various factors in pipelines, protecting pipes and equipment from damage. Suitable for various water supply and drainage systems in industrial plants, enterprises, high-rise buildings, power stations, and similar facilities, it utilizes the expansion and contraction of air within the piston's upper chamber to buffer sudden shock waves, thereby reducing their intensity. This maximizes the prevention of equipment damage caused by the immense force of water hammer impacts.
