Surge Relief Valve for Water, NPT, Bronze Body

Size: ½" to 2"
Valve Type: Surge Relief Valve
Fluid: Water

VAG GA Industries Figures 667-D and 667-U are direct acting, pressure balanced, spring loaded, globe body surge relief valves, designed to protect small water pump stations and systems from excessively high pressure due to a sudden stoppage of pumping or valve closure.

The valves are closed as long as the pressure at its inlet is below the spring setting but open as quickly as needed to discharge water out of the system at the rate necessary to prevent a further rise in pressure.The valve closes slowly and seals tightly when pressure decreases below the setting.

The valve is full ported and utilizes sensitive, responsive springs for maximum capacity with a nominal rise in pressure above set point.

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.
