Air Release valve

Air Release Valves, or Air Relief Valve function to release air pockets that collect at each high point of a full pressured pipeline. An air release valve can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure. This greater force opens the orifice whenever air pockets collect in the valve. Air Release Valves are essential for pipeline efficiency and water hammer protection.

Recommended in micro/drip irrigation systems as a safety valve to remove entrapped air and to break the vacuum in the system.
