Combination Air Valve for Water, Single Body

Size: 1/2" to 4"
Valve Type: Air Valve
Fluid: 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.

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.
