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.

Air vacuum valve.

Air vacuum valves feature cast iron construction and high low pressure resilient seating. Air vacuum valve is also used to discharge large volumes of air from the pipeline system when the pipeline is initially filled and after water column separation. 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. Floats and internal components are 316 stainless steel. 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 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. Apco full flow foot valves fff. Air vacuum valves allow large volumes of air to be exhausted from or admitted into a pipeline as it is being filled or drained.

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. They maintain system design efficiency and provide system protection.

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

Air release valves vacuum valves air vacuum valve air release valve. Air vacuum valve. 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. 10pcs 21 28 21.

Suitable for all high points in pumping stations venting and vacuum protection. Air valve used in this situation is an a r i.
