Lochinvar & A.O. Smith 100327628 Relief Valve
The Lochinvar & A.O. Smith 100327628 Relief Valve is a critical safety component designed for high-capacity commercial water heaters and boiler systems. This 3/4-inch pressure relief valve is factory-set to a 150 PSI relief setting, providing heavy-duty over-pressure protection for appliances with a thermal output up to 1,912,000 BTU/hr. Engineered with a corrosion-resistant brass body and stainless steel spring, this OEM replacement part ensures precise mechanical actuation when system pressure exceeds safe operating limits. It is the designated direct replacement for 100277759, maintaining the exact physical footprint and discharge capacity required for Lochinvar and A.O. Smith equipment. As a veteran HVAC technician, you know that matching the BTU rating and NPT connection size is non-negotiable for ASME compliance. This valve is built to handle the high-stress demands of hot water storage tanks and industrial hydronic loops.
Key Benefits for the Contractor
- Direct OEM Compatibility: Specifically engineered as a drop-in replacement for Lochinvar 100327628 and A.O. Smith 100277759, eliminating field modifications.
- High Discharge Capacity: Rated at 1,912,000 BTU, making it suitable for large-scale commercial boilers and high-recovery water heaters.
- Built for Longevity: Features a high-quality brass body and internal components designed to resist scale buildup and thermal fatigue in hot water systems.
- Standardized Fit: Utilizes 3/4" NPT connections for easy integration into existing relief lines and discharge piping.
Common Questions
Is this valve a suitable replacement for the 100277759 model?
Yes, the 100327628 is the official direct replacement for the legacy 100277759 relief valve. It maintains the same 150 PSI rating and 1.9M BTU capacity.
Can this be used on steam boilers?
This specific model is designed for water heaters and hot water boilers. Always verify that the BTU/hr rating of your heating appliance does not exceed the relief valve's 1,912,000 BTU capacity.
Why is the 150 PSI rating important?
The 150 PSI rating must match the Maximum Allowable Working Pressure (MAWP) of your tank. Using a valve with an incorrect pressure setting can lead to premature leaking or catastrophic tank failure.
