done when the steam pressure is at approximately 75 percent of the safety-valve set pressure. Safety and safety-relief valves on low-pressure boilers should be tested at least quarterly, this is in accordance with the National Board Inspection Code. Blow-down valves – The concentration of solids in the boiler should be measured and the boiler blown-down at such intervals as necessary to maintain established limits. Blow-down valves are placed at the lowest point of the boiler …

There is no routine maintenance on a safety valve. However, safety valves are routinely tested to ensure proper operation. Safety valves are commonly tested by lifting the safety valve try lever. With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve …
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.
Safety Valves. Often considered the primary safety feature on a boiler, the safety valve should really be thought of as the last line of defense. If something goes wrong, the safety valve is designed to relieve all the pressure that can be generated within the boiler.
