The Figure 5325 Single Acting (One Way Flow) Altitude Valve is a self-contained, pilot-operated, diaphragm actuated level control valve that closes tight to prevent overflow in elevated tanks, standpipes and storage reservoirs without the needs for floats or level sensors. The valve is installed in the fill line and is used when the tank supplies the distribution system through a separate line.The valve is equipped with a solenoid pilot to intercept the valve operation and close the main valve upon electrical signal. An optional check feature can be provided to close the main valve upon pressure reversal and the optional delayed opening feature allows the tank to be drawn down 3 to 20 ft.before the valve opens to refill the tank.
The valve is available full port globe body up to 16" size and reduced port globe to 10". Full port angle body valves are available to 10". NPT threaded connections 1-1/2" to 3" and ANSI Class 150 or 300 flanged connections from 2" to 16".

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.
