Model 125 Booster Pump Control Valve

Model 125 Booster Pump Control Valve

The Model 125, primarily designed for use with centrifugal booster pumps, can also be used on well pumps with relatively shallow lifts where the pump design permits starting against a closed valve.


  • Eliminates surges associated with starting and stopping the pump
  • Pump starts against a closed valve that gradually opens at a controlled rate
  • Valve gradually closes at a controlled rate while pump continues to run
  • Pump stops when valve is fully closed
  • Valve acts as a check valve in the event of pressure reversal (power failure)
  • Separate adjustable opening and closing speeds
  • Can be maintained without removal from the line
  • Factory tested
