Kammas 10pcs 1 2 mpt air vacuum relief valve provides instant air and vacuum relief vacuum breaker air vent drip irrigation z102 diameter.
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.
Air valves can contribute to the improvement of the efficiency of the water system.
As the pipeline fills fluid enters the valve raises the float and shuts off.
When draining the pipeline the float drops allowing air to enter preventing loss of pressure possible pipeline collapse and damaging water column.
An air vacuum valve is the right fit for this application because it can rapidly expel large volumes of air and close when fluid fills the air valve.
