Lochinvar & A.O. Smith 100110714 Valve

The Lochinvar & A.O. Smith 100110714 Valve is a 3/4" NPT Temperature and Pressure (T&P) relief valve engineered specifically for high-demand commercial water heaters and residential boilers. Designed to handle up to 150 PSI, this ASME-rated safety component provides critical over-pressure and thermal protection for the pressurized tank. This valve features a lower probe configuration with a 3/4 inch male threaded inlet and a 3/4 inch female threaded outlet, ensuring a secure NPT connection to the water heater tank. With a thermal relief set point at 210°F and high-capacity discharge ratings, the 100110714 replacement valve is the standard OEM part for A.O. Smith BTH series and Lochinvar Knight boilers. The corrosion-resistant brass body and spring-loaded mechanism ensure consistent safety relief performance in aggressive water conditions, preventing catastrophic tank failure and maintaining system integrity throughout the heating lifecycle.
