Fulton Boiler 171180 Pressure Proving Switch

The Fulton Boiler 171180 Pressure Proving Switch is a monitoring component that verifies proper air or gas level conditions within boiler and burner systems before operation begins. This switch's value changes and activates the control circuit when specified swell levels are reached, allowing connected equipment to operate under approved conditions. It operates as a safety and operational control part by preventing ignition or burner activity during improper airflow conditions. It is installed in commercial boilers, burner assemblies, combustion systems, and industrial HVAC systems, heating equipment, where regulated air pressure verification is required for system operation and equipment sequencing.
