  • How to Select and Size Safety Valves and Pressure

    The set pressure, which is measured in pounds per square inch (PSIG), is the pressure at which a safety or pressure relief valve opens. The set pressure of the valve must not exceed the maximum allowable working pressure (MAWP) of the boiler or other vessel. What this means is that the valve must open at or below the MAWP of the equipment. In
