Pressure-relief valves for use with air, inert gas, and liquids open automatically when pressure in a system builds up and exceeds a preset limit. Select valves are rated by The American Society of Mechanical Engineers (ASME) to designate their intended function under normal operating conditions.
ASME Section VIII & XIII Air, Inert Gas & Liquids Pressure Relief Valves
Pressure-relief valves for air, inert gas, and liquids comply with ASME Section VIII codes, which certifies they are designed, tested, and inspected to comply with minimum industrial safety standards. These valves pair with fired and unfired pressure vessels.

Non-Code Air, Inert Gas & Liquids Pressure Relief Valves
These non-code pressure-relief valves are calibrated to factory specifications based on the manufacturer’s rated working pressure (MRWP). They are often used for residential and non-public applications where ASME-rated valves are not required.
