FA49H explosion-proof valve is a water safety valve that can block water hammer and eliminate destructive water hammer. Usually installed in the front of the engineering pipeline, consisting of a number of safety valves and a buffer spring structure, when the water hammer is formed but does not cause damage, the buffer spring will dissolve the water hammer when the formed water hammer is sufficient to destroy the subsequent equipment, the safety valve group acts. The equipment behind the explosion proof wave valve is prevented from being impacted by water hammer, so that the system is protected and the facilities operate normally. The valve is safe and reliable, without detonating after detonating, and it can be used continuously and has long service life.
