Xylem-McDonnell & Miller 193-B Low Water Cut-Off & Pump Controller 1.25" Tap, 3/4" Gauge Glass, 163600

The Xylem-McDonnell & Miller 193-B 193W/1.25 Inch Taps, 3/4 Inch G.Gl.163600 is a pressure switch designed to adjust water pressure in a variety of HVAC equipment, particularly boilers. It acts as an automatic on-off switch, sensing water pressure changes and activating the system when pressure falls below a preset threshold or turning it off when pressure exceeds a predetermined limit. This helps to maintain ideal pressure levels within the boiler, reducing damage caused by either excess or inadequate pressure. The Xylem-McDonnell & Miller 193-B product has 1.25-inch taps for connection and a 3/4-inch female gas line connector. Its adjustable differential settings provide exact control over the pressure activation points, resulting in efficient and safe boiler operation. This pressure switch is often found in several Xylem-McDonnell & Miller boiler models.
