Lochinvar & A.O. Smith 100208448 Relief Valve
The Lochinvar & A.O. Smith 100208448 Relief Valve is a critical boiler and water heater safety component designed for precise overpressure protection. This heavy-duty 1-inch NPT inlet valve features a 1-1/4 inch outlet and is factory-calibrated to a 50 PSI set pressure. Engineered for high-recovery commercial and residential hydronic systems, it effectively prevents vessel failure by automatically discharging excess pressure when system limits are exceeded. As an OEM replacement part, the 100208448 ensures seamless compatibility with Lochinvar boilers and A.O. Smith water heaters, maintaining the specific flow capacities required by the original equipment manufacturer. This pressure relief valve is constructed with corrosion-resistant internals to handle demanding heating cycles and high-temperature water applications. For technicians performing scheduled maintenance or emergency repairs, utilizing this 50# relief valve ensures the system remains within ASME safety standards without the risk of sub-optimal "will-fit" performance issues.
Key Benefits- Precise 50 PSI Calibration: Pre-set to deliver reliable opening at exactly 50 pounds per square inch to safeguard against structural damage.
- High-Flow Capacity: Features an oversized 1-1/4 inch discharge port to maximize volume relief during critical overpressure events.
- Durable OEM Construction: Manufactured to the exact specifications of Lochinvar and A.O. Smith for superior seat sealing and longevity.
- Broad Compatibility: Directly replaces legacy and current part numbers in a wide range of commercial water heating and boiler models.
What are the connection sizes for the 100208448?
This valve utilizes a 1-inch female NPT inlet for connection to the heater or boiler and a 1-1/4 inch female NPT outlet for the discharge piping.
Can this valve be used in systems with an operating pressure of 45-50 PSI?
No. To prevent simmering or nuisance tripping, the system's maximum operating pressure should typically remain at least 10% below the 50 PSI relief setting.
Is this relief valve suitable for steam applications?
The 100208448 is specifically designed for water heating and hydronic boiler systems; always verify the media and BTU rating on the nameplate before installation.
