GA Industries Figures 7100-D and 7100-U are self-contained, pilot-operated, differential piston actuated solenoid valves.The main valve fully opens when the solenoid pilot is de-energized and closes tight when the solenoid pilot is energized.
The rugged full port main valve provides maximum capacity and is available in either globe or angle body for piping versatility.Its unique V-port trim provides an excellent flow characteristic.Closing speed is controlled by a needle valve to minimize pressure surge and waterhammer.
The main valve can be supplied with an OPTIONAL "stop-check" piston to prevent return flow should the inlet pressure fall below the outlet pressure.

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.
