Electric Check Pump Control Valve

Size: 3" to 36"
Valve Type: Pump Control Valve
Fluid: Water

GA Industries “Electric Check” pump control valves are installed on the discharge of water pumps to minimize pressure surges associated with pump starting and stopping.They are self-contained, differential piston actuated valves and utilize line pressure for operation.A system of valve mounted electro-hydraulic controls sequences the operation of the valve with that of the pump motor.

The valve’s unique V-port trim provides semi-linear flow control while opening and closing for ideal surge control plus full port capacity to minimize head loss while the pump is in operation.

The Electric Check pump control valve has independently adjustable normal opening, normal closing and emergency closing speeds so the valve can be “tuned” to minimize surges under all operating conditions.

The electrical logic necessary to interface the valve with the motor control center can be provided by others or by using the GA Industries Pump Director pre-wired control panel.

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.
