Air Release Valves, Vacuum Valves, Air Vacuum 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.

Vacuum Valves

A Vacuum Valve, or Air Vacuum Valve is a safety valve opening inward to admit air to a vessel in which the pressure is less than that of the atmosphere, in order to prevent collapse.
