More about this product

The McDonnell & Miller 7B is a highly reliable, electric switch assembly engineered for commercial and industrial steam boilers, deaerators, and large feed tanks. Operating as a modulating level control component, it integrates seamlessly into combination low-water cut-off and pump controller heads, such as the Series 93, 193, 94, and 194. What sets the 7-B apart from standard on/off switches is its built-in 135-ohm slide-wire potentiometer, which sends a proportional control signal to regulate modulating feedwater valves.

Details:

  • For use with 93/193 and 94/194 series pump controller/low water cut-off
  • Equipped with auto reset
