GA Figure 920:

Air Release Valve for Water, Compound Lever

Size: 1" and 2"
Valve Type: Air Valve
Fluid: Water

VAG GA Industries Figures 920 and 920H are used to minimize the build up of air in water pipes and systems by automatically and efficiently releasing air that has collected in the valve while under pressure and operational.Typically installed at high points where air naturally collects, the valve opens when sufficient air has accumulated in the valve and closes tightly after the air has been released.

Figures 920 and 920H are also installed on the top of the volute of split case pumps, on pressure filters and any place where it's necessary to automatically release air for efficient system operation.

Clean Water

Dependable valves that meet your clean water needs

From the raw water intake to the filtration plant to the finished waster distribution and storage system, GA Industries valves have been providing dependable service in large and small water systems. GA Industries pump control, check and relief valves mitigate damaging pressure surges and eliminate slam and bang that can result from the operation of water pumps.

Our full range of pilot operated control valves regulate distribution system pressure and prevent overflow of storage tanks and reservoirs. Air trapped in water pipelines can reduce system efficiency and exacerbate pressure surges. Our wide range of automatic air valves ensures we have the right valve to maintain an air free system.

And when it’s necessary to isolate a pump, process or section of pipeline, you can depend on GA Industries butterfly valves for reliable flow shutoff.
