FH49H-Q(A9H-Q) Explosion proof Wave ValveDetailed product description：

FA49H explosion-proof wave valve is a device used to eliminate water hammer shock waves caused by multiple reasons in pipelines and protect pipelines and equipment from damage. Suitable for various water supply and drainage systems such as industrial and mining, enterprises, high-rise buildings, and power stations, it utilizes the expansion and contraction of air in the piston chamber to buffer sudden shock waves and alleviate their intensity, minimizing equipment damage caused by huge water hammer impact. The device has a simple structure, excellent material selection, and long service life.
