  • Boiler Safety - Minnesota Department of Labor and Industry

    – The safety valve is the most important valve on the boiler. Safety valves prevent dangerous over pressurization of the boiler. Safety valves are installed in case there is failure of pressure controls or other devices designed to control the firing rate. All safety valves should be kept free of debris by testing the safety valve regularly.Learn More

  • CHAPTER TWO: Boiler Operation Maintenance & Safety Study …

    3. Safety Valve: The function of the safety valve is to prevent the increase of steam pressure in the holler above its design pressure. When the pressure increases above design pressure, the valve opens and discharges the steam to the atmosphere. When this pressure falls just below design pressure, the valve closes automatically.Learn More
