Water Supply Products

A.R.I. air valves are an integral part of a water transmission system. These air valves will discharge air from a non–pressurized pipe enabling the efficient filling of the pipeline; continuously release air from a pressurized system, preventing the build-up of air pockets in the pipeline and admit large amounts of air into the system when vacuum conditions occur, protecting the pipeline from pressure transients and possible collapse.
