Temperature and pressure-relief valves open automatically when pressure and temperature levels in a system exceed a preset limit. Also called T&P valves, they open and relieve pressure and temperature in hot water tanks and heaters used in commercial and residential areas. Select valves are rated by The American Society of Mechanical Engineers (ASME) to designate their intended function under normal operating conditions.
ASME Section IV Temperature & Pressure Relief Valves
Temperature and pressure-relief valves comply with ASME Section IV codes, which certifies they are designed and constructed to meet minimum industrial safety standards. These valves pair with low-pressure steam boilers and hot-water boilers.

ASME Section XIII Temperature & Pressure Relief Valves
Temperature and pressure-relief valves for air, inert gas, and liquids comply with ASME Section XIII codes, which certifies they protect against excessive pressure conditions that may damage pressurized equipment. These valves pair with boilers, pressure vessels, and piping systems to control temperature and pressure and meet minimum industrial safety standards.

Non-Code Temperature & Pressure Relief Valves
These non-code temperature and 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.
