Double Ball Air Relief Valve , Flange End Air Pressure Release Valve
Products Description
Air Release Valves function to release air pockets that collect at each high point of all pressured pipeline. Air Release VAlves 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.
