GA Industries Series 5000 are pilot-operated, diaphragm actuated water control valves.GA Figure 5470 Pressure Reducing and Sustaining Valves perform two independent functions.As long as the upstream pressure is higher than the minimum set on the sustaining pilot it will reduce a higher fluctuating upstream pressure to a steady, lower downstream pressure regardless of fluctuations in demand.However, should the upstream pressure fall to the minimum, the sustaining pilot takes over and throttles to maintain the minimum upstream pressure.
Standard features include pilot wye-strainer and isolating valves and inlet and outlet pressure gauges.Many optional features and accessories are available.
The valve is available with full port globe body up to 16' size or reduced port globe in 3" to 10" sizes, NPT connections to 3" and Class 150 or 300 flanged from 2" to 16".Full port angle body valves are also available.

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.
