Air/Vacuum Valve

Brand: Apco
Does not ship to Virginia, United States
Air/Vacuum Valves are float operated and have a large discharge orifice equal in size to the valve’s inlet.
Air/Vacuum valves allow large volumes of air to be exhausted from or admitted into a pipeline as it is being filled or drained. As the pipeline fills, fluid enters the valve, raises the float and shuts-off. 
When draining the pipeline, the float drops and allows air to enter, preventing a vacuum and possible pipeline collapse or damaging water column separation.
