GA Industries Figure 517 are standard rectangular port non-lubricated, rubber seated eccentric plug valves with a minimum of 80% port area.The valves fully meet the requirements of AWWA Standard C517 and are typically used for isolation service in sewage and wastewater systems and treatment plants.
The valve's rugged iron body has a weld overlaid corrosion resistant nickel seat.A Buna-N rubber coating is transfer molded and vulcanized to the ductile iron plug.The plug is supported by upper and lower PTFE coated 316 stainless steel bearings that ride in a 316 stainless steel bushing in the body and bonnet.
Figure 517 standard rectangular port plug valves seat tightly up to rated pressure in both directions.
The valve can be actuated by a quarter-turn manual worm gear or an electric motor operator.Operators are selected and sized based on operating conditions, factory mounted on the valve and tested as an assembly.

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.
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.
