Lochinvar & A.O. Smith 100111923 Relief Valve
The Lochinvar & A.O. Smith 100111923 is an industrial-grade pressure relief valve engineered for high-output hydronic heating and potable water systems. Featuring a large 1-1/4 inch NPT connection, this valve is designed to manage thermal expansion and prevent over-pressurization in large-scale boilers and water heaters. It is factory-set to a 50 PSI discharge threshold with a high-flow 2,490,000 BTU/hr capacity, ensuring it can handle the rapid pressure spikes common in heavy-duty HVACR equipment. This component serves as a direct replacement for A.O. Smith 9007333005, maintaining the safety and operational integrity of your commercial systems. Built with a robust brass body and a precision stainless steel spring, it provides the reliability required by veteran contractors for critical pressure management. Correct installation of this safety relief valve is essential for protecting heat exchangers and piping from catastrophic failure caused by excessive internal pressure.
Key Benefits- High Discharge Capacity: Rated for up to 2,490,000 BTU/hr, making it suitable for high-volume commercial boilers and water heating systems.
- Precise Pressure Control: Pre-calibrated at 50# (PSI) to provide consistent protection against system over-pressurization.
- Broad Compatibility: Serves as an OEM replacement for Lochinvar and A.O. Smith units, as well as State and American Water Heaters.
- Durable Construction: Heavy-duty brass housing resists corrosion while the internal spring mechanism ensures long-term seating reliability.
What is the connection size for the 100111923?
This valve features a standard 1-1/4" threaded inlet and outlet designed for high-flow piping configurations.
Can this valve be used for steam applications?
This specific model is primarily designed for hot water heating systems and water heaters. Always verify the ASME rating on the valve tag for specific medium compatibility.
Is this a direct replacement for obsolete A.O. Smith parts?
Yes, the 100111923 is the current recommended replacement for the obsolete 9007333005 relief valve.
