Conbraco Industries 18C-521-3-150 Temperature & Pressure Relief Valve
The Conbraco Industries 18C-521-3-150 is a heavy-duty Temperature and Pressure (T&P) Relief Valve engineered to provide critical overpressure and overtemperature protection for water heaters and hydronic heating systems. With a robust 1″ Male NPT inlet and 1″ Female NPT outlet, this valve integrates seamlessly into standard plumbing configurations, making installation straightforward for HVAC and plumbing professionals alike.
Pre-set at 150 PSI and 210°F, the 18C-521-3-150 automatically opens to discharge excess pressure or temperature before dangerous conditions can develop, safeguarding equipment, piping, and building occupants. Its impressive 2,155,000 BTU capacity ensures it can handle the demands of high-output water heating and hydronic applications. The 3″ probe length allows for accurate immersion sensing within the water heater tank or boiler vessel, enabling fast and reliable response to rising temperatures.
