Watts 0121344 is a 3/4" lead free temperature and pressure relief valve that gives automatic protection to hot water supply tanks and water heaters up to 105,000 BTU/hr.
This two-in-one valve guards against excessive temperature and pressure in emergency conditions. It has a lead free copper alloy body with an NPT male inlet and NPT female outlet, a thermostat with a special thermo-bonded coating on a 4" extension, and a test lever. Temperature relief is 210°F (99°C) and pressure relief is set at 175 psi (12.07 bar). It is ASME rated and CSA listed.
Before ordering, confirm the heater or tank input is no more than 105,000 BTU/hr, that the 175 psi setting does not exceed the heater's rated working pressure, and that the 4" thermostat extension suits the tank opening.
