Tilting Disc Check Valve, With Top Dashpot

Size: 3" to 36"
Valve Type: Check Valve
Fluid: Water

The GA Industries Tilting Disc Check Valve features a streamlined design and full flow area for lower full open head loss than conventional swing check valves.Its energy efficient operation is combined with a short 40-degree disc stroke that provides quick closing valve 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.

The top mounted oil dashpot is mechanically attached to the valve disc.Its self-contained hydraulic system controls the valve's opening and closing speed over its full stroke with an independently adjustable final closing speed engaged during the last 10% of closure.Reverse flow occurs during closure which can reduce pressure surge.The top mounted dashpot is recommended when there is likelihood of extremely rapid flow reversal.

Clean Water

Dependable valves that meet your clean water needs

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.
