GA Figure 920 Air Release Valve for Water, Compound Lever.

1" and 2"

Productgroup: Air Valves

Medium: 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.
