Air release valves are installed on the top of the pump casings and arranged for automatic or remote-control operation.
The purpose is to release trapped air in the casing and to minimize pump cavitation. An automatic air release is desirable on any pump with a casing that is normally full of water.
Air release valves are also used in the wet pipe sprinkler systems to exhaust as much trapped air as possible from a single location every time the system is filled. then it will reduce the amount of oxygen trapped in the system that will fuel corrosion and microbial activity.
