GA Industries Figure 3400-D Altitude Valves are self-contained, hydraulically operated, differential piston actuated valves and function without electricity.The valves are installed on the tank fill line and close when the tank is full to prevent overflow and automatically re-open to replenish the tank when the water level falls 6” to 12” below maximum.
The Figure 3400-D incorporates a “stop-check” feature in the main valve to prevent reverse flow through the valve, independent of the hydraulic controls

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.
