Maintain precise water level control in your commercial steam boiler with the 173003 replacement head mechanism. Engineered specifically for the 150S-HD series, this component provides a streamlined solution for servicing existing low-water cut-off and pump control units without requiring a complete piping overhaul.
The head mechanism functions as the primary sensing and switching interface, utilizing a high-performance internal linkage to translate float position into reliable electrical signals. By replacing the head assembly, you ensure that the internal switches and contacts remain responsive to fluctuations in boiler water levels, effectively preventing dry-firing and maintaining consistent operational safety.
