A flow switch helps confirm water movement in a compatible system before connected equipment operates, and this Grid Controls M-25 version is a 25 amp 115 volt model with a 1-1/2 inch slip connection using the 57-F3-2500-WHT reference. A switch in this class is useful when a stronger-rated control component is needed for dependable flow-based operation.

The higher amp rating gives this part practical value because some systems require a more robust switch than lighter-duty control-only versions. A properly selected flow switch helps support cleaner flow verification and contributes to more dependable heater or equipment protection.

This type of part is especially useful when replacing a heavier-duty flow switch that has become unreliable or non-responsive. That helps restore the intended operational safeguards while keeping the system layout familiar.

Installed in the proper application, this flow switch helps support dependable flow detection and cleaner overall equipment control.

  • M-25 flow switch rated at 25 amps and 115 volts with 1-1/2 inch slip connection
  • Helps verify flow before connected equipment operates
  • Useful in higher-rated control applications
  • Supports cleaner system protection and equipment logic
  • Improves control reliability and service confidence
