GA Figure 945 Combination Air Valve for Water, Single Body

1/2" to 4"

Productgroup: Air Valves

Medium: Water

VAG GA Industries Figures 945-T Combination Air Valves are “triple function” valves. They vent air from pipelines and systems as they are being filled with water and then close tight once the system is full and pressurized. They also release air that accumulates in the valve while the system is operational. And, they automatically open to admit air to limit vacuum formation when the pipeline or system is drained and/or a negative pressure occurs in the valve.

The Figure 945-T Combination Air Valves are typically installed at high points in the system where air naturally rises during filling and in operation and vacuum first forms during draining.
