Xylem-McDonnell & Miller 1575 High-Pressure Level Control 171907

The Xylem-McDonnell & Miller 1575 Hi Pressure Level Control 171907 is an essential safety device for hydronic heating systems, notably boilers. By monitoring water pressure and cutting off the fuel supply if it rises above a safe level, it functions as a high-pressure limit switch. By doing this, overpressurization of the boiler, possible explosions, and equipment damage are avoided. An internal switch is triggered by the pressure-sensitive diaphragm of the gadget when the pressure exceeds the predetermined limit. The electrical circuit that supplies fuel to the burner is then cut off, which puts an end to the burner's activity. Typically, the 1575 type has an adjustable setpoint that enables customization for different boiler models and operating pressures. In general, by averting hazardous overpressure scenarios, hydronic heating systems.
