Air/Vacuum Clean Water Valves

Air/Vacuum Valves, often referred to as "large orifice valves", are used to allow large volumes of air to be exhausted from or admitted into a water pipeline as it is being filled or drained. When draining the pipeline, the float drops, allowing air to enter, preventing loss of pressure, possible pipeline collapse and damaging water column separation..
