Lochinvar & A.O. Smith 100110719 Valve

Professionals in the field know that managing thermal expansion and overpressure in high-capacity systems requires a reliable Lochinvar & A.O. Smith 100110719 Valve. This genuine OEM Temperature and Pressure Relief Valve is engineered for heavy-duty commercial applications, featuring a substantial 2,155,000 BTU/hr capacity. Designed with a 1-inch Male NPT inlet and a 1-inch Female NPT outlet, this T&P Relief Valve ensures a high-flow discharge during critical safety events. The integrated 4-inch element provides precise thermal sensing, while the factory setting of 150 PSI provides a robust threshold for commercial water heater pressure relief. This component is a critical safety upgrade for BTH, SUF, and HCG series units, maintaining system integrity by preventing catastrophic tank failure through automatic mechanical venting when environmental limits are exceeded.

• High BTU Rating: Capable of handling up to 2.155 million BTUs, making it suitable for large-scale commercial boilers and heaters.
• OEM Precision: Guaranteed compatibility with specific A.O. Smith and Lochinvar models, ensuring correct thread engagement and sensing depth.
• Robust Construction: Built to withstand the rigorous demands of 150 PSI systems without premature fatigue or leaking.
• Extended Probe: The 4-inch immersion element ensures accurate core temperature monitoring for rapid response.

What models are compatible with the 100110719 valve?
This valve is specifically designed for high-capacity commercial gas heaters, including the Lochinvar and A.O. Smith BTH (Cyclone), SUF, and HCG series with inputs up to 2.155mBTU.

Can I use a 3/4-inch T&P valve instead of this 1-inch model?
No. You must never undersize a relief valve. The 1-inch connections are necessary to meet the discharge capacity requirements of the high-output commercial units this part is rated for.

Why is the 4-inch element length important?
The element must extend far enough into the tank to accurately sense the hottest water near the top. A shorter probe might delay opening, risking over-temperature conditions.
