AirCushioned Swing Check, Lever & Weight

Size: 3" to 48"
Valve Type: Check Valve
Fluid: Wastewater, Water

GA Industries Figures 250-DS and 250-US heavy duty, customizable swing check valves utilize an adjustable counterweight for rapid closure combined with a highly engineered air cushion chamber to provide non-slam operation.

Typically installed on the discharge of a pump to prevent backflow when the pump is off line, it opens smoothly at pump start and closes quickly and quietly upon pump shutdown.

Especially designed to withstand the rigors of pump station operation, the Figures 250-DS and 220-US meet the design, materials of construction and testing required by AWWA C508 and are suitable for use with water or sewage.

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.

Wastewater

Reliable wastewater valves designed for rigorous service

GA Industries sewage and wastewater valves are specially designed to accommodate the rigorous demands of the sewage collection, pumping and treatment process.

Whether a large regional sewage pump station, a small lift station or in-plant process pumping, GA Industries line of wastewater check, pump control and surge relief valves provide reliable service under difficult operating conditions. GA Industries ECO-Centric® plug valves handle solids and stringy material and are used in sewage and wastewater systems for pump, pipeline or process isolation.

Our full range of sewage and wastewater air valves automatically release air and sewage gas from forcemains to maintain pumping efficiency and minimize pipeline corrosion.
