Temperature and pressure relief valves are used in residential and commercial water heater and hot water storage tank applications to provide automatic temperature and pressure protection to hot water supply tanks and hot water heaters.

T&P valves used on residential water heaters are typically designed and manufactured to relieve pressure at 150 psi and temperature at 210 degrees F. ASME, ANSI and CSA (AGA) approved relief valves protect the water heater from excess pressures and …

the system. When the T&P relief valve senses this excess pressure, it opens relieving the thermal expansion* and returning the pressure back to normal conditions. Second, they respond to excessive tem-perature. When the temperature of the water in the water heater reaches 210°F, the T&P relief valve’s internal thermostatic

This valve has an extended inlet shank for water heaters with up to 2 inch insulation. ASME rated and CSA listed. Temperature relief is 210 degrees F (99 degrees C) and the pressure relief is 100 psi (7.03 bar).

This 3/4 inch extended shank temperature and pressure relief valve is used in water heater and hot water storage tank applications to provide automatic temperature and pressure protection to hot water supply tanks and hot water heaters up to 105,000 BTU/hr.
