Resideo PA404A1025 Pressure Controller W/Subtractive Differential 3-15 PSI

The Resideo PA404A1025 is a pressure control device that is used to provide safe steam heating boilers. This control is suitable for use in regulating and sustaining the right pressure within the boiler system since it comes with a pressure range of 3 to 15 PSI and a subtractive differential pressure mechanism. Its main purpose is to protect the boiler from pressure rise that may be hazardous to the machinery or lead to the formation of dangerous conditions and regulate the burner in and out depending on the set pressure levels.
