The GA Industries Tilting Disc Check Valve features a streamlined design and full flow area for lower head loss than conventional swing check valves.Its energy efficient operation is combined with a short 40-degree disc stroke that provides quick closing to minimize hammer.The valve employs offset seating technology to smoothly lift the disc off of the seat during opening and into the seat during closing without binding or sticking.
If flow reversal occurs, the offset disc design divides the disc so that hydraulic forces acting on the upper third of the disc counteract the forces acting on the lower two thirds for an inherent cushioning effect.
The bottom buffer is a hydraulic dashpot that further minimizes hammer by decelerating the final 10% of the disc's closure in situations where rapid flow reversal occurs, such as multiple pumps and/or short pipes.

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.
