Air vacuum valve.

An air vacuum valve can be piped to the top of the pump column so that when the pump is started the air trapped in the pump column is expelled through the air vacuum valve figure 4. System efficiency is maintained by venting air via the air valves from the system that can restrict flow and increase pumping costs. When draining the pipeline the float drops and allows air to enter preventing a vacuum and possible pipeline collapse or damaging water. Use in water distribution and transmission and vacuum protection.

Air valves can contribute to the improvement of the efficiency of the water system.
