GA Industries
The Figure 5320 Single Acting (One-Way Flow) Altitude Valve is a self-contained, pilot-operated, diaphragm actuated level control valve that prevents overflow in elevated tanks, standpipes and storage reservoirs without the need for floats or level sensors. The single acting valve is installed in the tank fill line. Water flows out of the tank through a separate line to supply downstream demand or through a bypass check valve around the altitude valve when demand is upstream of the tank and supply head falls below tank head.
An optional "delayed opening" feature can be provided to allow the tank to draw down 3 to 20 ft.before the valve opens to refill the tank.
An optional "check" feature can be provided to prevent back flow through the altitude valve should supply head fall below tank head.
The valve is available full port globe body from 1-1/2" to 16" size and reduced port globe in sizes 4" to 10". Sizes to 3" are available NPT or flanged, sizes 4" to 16" are available flanged only.

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.
