Lochinvar & A.O. Smith 100208450 Valve

The Lochinvar & A.O. Smith 100208450 Valve is a critical safety component engineered for high-performance residential and commercial HVAC systems. This heavy-duty boiler pressure relief valve is factory-set to a 75 PSI discharge threshold, providing essential protection against over-pressurization in water heaters and hydronic heating loops. Featuring a 3/4" NPT inlet and a 1" NPT outlet, it ensures high-capacity flow during emergency relief cycles to maintain vessel integrity. Designed as a direct OEM replacement for Lochinvar and A.O. Smith equipment, it eliminates compatibility issues often found with universal alternatives. This HVAC replacement part is built to withstand the rigors of mechanical rooms, ensuring consistent blow-down performance and reliable reseating. For contractors performing furnace repair or boiler maintenance, installing this genuine 75# relief valve is a standard best practice to meet local plumbing codes and safeguard the system from thermal expansion. Trust the 100208450 for precise pressure relief and long-term durability in demanding hydronic applications.

Key Benefits
  • OEM Compatibility: Precision-engineered for a seamless fit in Lochinvar and A.O. Smith boilers and water heaters.
  • Optimized Flow: Oversized 1" outlet allows for rapid pressure dissipation exceeding standard 3/4" discharge capacities.
  • Factory Calibrated: Accurate 75 PSI set point prevents premature weeping while ensuring immediate response to spikes.
  • Durable Construction: High-grade materials resist mineral buildup and corrosion in closed-loop heating environments.
  • Code Compliance: Meets essential safety requirements for pressurized vessels in residential and light commercial settings.
Common Questions
  • Will this valve stop my boiler from leaking? If the current valve is "weeping," it may be due to thermal expansion or sediment on the seat. Replacing it with a new 100208450 often resolves the issue if the seat is compromised.
  • Can I use this on a system rated for 150 PSI? No. This valve is specifically for 75 PSI limits. Always match the relief valve rating to the maximum working pressure of your tank or boiler.
  • Is the discharge pipe size important? Yes. To prevent backpressure, ensure your discharge piping is at least 1" to match the valve's outlet, and never reduce the pipe diameter.
