Lochinvar & A.O. Smith 100208444 Valve

The Lochinvar & A.O. Smith 100208444 Valve is a technical-grade Temperature and Pressure Relief Valve designed for high-capacity water heating and boiler systems. As a veteran-preferred component, this 3/4" T&P Relief Valve is calibrated to lift at 150 PSI and 210°F, providing critical safety by venting excess thermal expansion. It features a 3-inch element and a high-efficiency flow rate rated at 1,912,000 BTU/hr (1.912mBTU), making it suitable for larger residential and light commercial units. This part is a direct manufacturer-authorized replacement for original RLV2007 and RLV2007K models. Whether you are performing a routine inspection or emergency service, utilizing this genuine OEM part ensures the system remains compliant with ASME and ANSI Z21.22 safety standards. Its heavy-duty brass construction is built for long-term service in demanding environments where pressure stabilization is paramount.

Key Benefits for Contractors:

• Direct Compatibility: Seamlessly replaces obsolete part numbers RLV2007 and RLV2007K without requiring piping modifications.
• High Thermal Capacity: Rated for systems up to 1.912 million BTU/hr, providing versatile protection for various A.O. Smith and Lochinvar models.
• Precise Pressure Management: Factory-set to 150 PSI to prevent catastrophic failure from over-pressurization.
• Professional Durability: Engineered for industrial service, ensuring the T&P relief valve discharge functions reliably under extreme thermal stress.

Common Questions regarding the 100208444:

What causes a T&P relief valve to drip constantly?
Constant dripping often indicates excessive thermal expansion or high static water pressure exceeding 80 PSI. Ensure a thermal expansion tank is installed and properly charged for the system's volume.

Does this valve come with a 3-inch shank?
Yes, this model features a 3-inch element/probe, which is the standard depth for most Lochinvar boiler and A.O. Smith water heater 3/4-inch ports.

Is the 100208444 interchangeable with other 3/4" valves?
While the thread size is common, the 1.912mBTU rating is specific to certain high-capacity models. Always verify that the BTU rating of the replacement valve meets or exceeds the input rating of the appliance.
