It is set in the factory and opens automatically when the pressure in the system is above the set point and closes when the pressure returns to a safe level. This is often used on industrial boilers in HVAC systems to ensure safe operation. It is a safety element in the heating system, that prevents over pressurization of equipment and ensures efficient operation.
