Lochinvar & A.O. Smith 100208445 Relief Valve
The Lochinvar & A.O. Smith 100208445 Relief Valve is a critical safety component engineered specifically for high-power commercial heating systems, including the CHV and CHH 0150 - 1000 series commercial electric water heaters. This 3/4 inch NPT temperature and pressure relief valve is factory-set at a 125 PSI pressure rating to ensure rigorous overpressure protection in demanding hydronic environments. With a substantial 1,619,000 BTU/HR rating, it effectively manages thermal expansion and prevents system overloads in large-scale boiler and water heating applications. Built to meet ASME safety standards, the 100208445 features a durable bronze body and is an essential OEM replacement part for maintaining the operational integrity of A.O. Smith and Lochinvar commercial boilers. For technicians performing preventative maintenance or emergency repairs, verifying the set pressure and connection size against the system nameplate is vital to ensure maximum safety and code compliance in industrial plumbing systems.
Key Benefits for the Contractor- Precise Overpressure Protection: Factory-calibrated to 125 PSI to prevent catastrophic failure in commercial electric water heaters.
- High Thermal Capacity: Rated for up to 1,619,000 BTU/HR, making it suitable for high-output heating systems.
- Direct OEM Compatibility: Specifically designed for Lochinvar CHV/CHH and A.O. Smith hi-power units, ensuring a perfect fit without field modifications.
- Standardized Threading: Features a 3/4" NPT connection for seamless integration into existing commercial plumbing manifolds.
When should the 100208445 relief valve be replaced?
Replace the valve if you notice persistent "simmering" or leakage, which typically indicates the seat is fouled or the internal spring has weakened. In commercial settings, regular inspection is required to ensure the safety relief valve activates at the designated 125 PSI set point.
Is the Lochinvar 100208445 lead-free?
No, this specific model is generally not rated as lead-free and is intended for commercial heating and boiler applications rather than potable water systems where lead-free compliance is mandated by local codes.
Can I use this on a system rated for 150 PSI?
No. You must never install a relief valve with a pressure rating lower than the system's maximum allowable working pressure (MAWP). Utilizing a 125 PSI valve in a 150 PSI system will result in premature lifting and system downtime.
