The GA Industries Figures 950 and 950H Combination Air Valves are "triple function" valves consisting of an air release valve factory piped to an air & vacuum valve.Air is vented through the air & vacuum valve's large orifice as the pipeline is filled with water and then it closes tight once the system is full and pressurized.The air release valve automatically opens and closes as often as necessary to vent air through its small orifice that collects in the valve while the system is pressurized and in operation.The air & vacuum valve opens to admit air through its large orifice to limit vacuum formation when the pipeline is drained and/or a negative pressure occurs in the valve.
The Figure 950 and 950H are standard with NPT threaded inlet and outlet.

Set-up NowFrom 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.
