Lochinvar & A.O. Smith 100110223 Gas Valve

The Lochinvar & A.O. Smith 100110223 Natural Gas Valve is a technical-grade 1.25" Gas Control Valve engineered specifically for high-capacity heating systems. Designed for precision in natural gas applications, this direct acting gas valve maintains stable combustion parameters by regulating fuel flow to the burner assembly. This OEM replacement part is critical for ensuring the safe operation of residential and commercial boiler systems and water heaters, effectively preventing gas leakage during standby cycles. As a specialized 1.25 NatGasValve, it is built to handle the higher volume inputs required by larger-scale HVACR equipment, providing the consistent manifold pressure needed for efficient thermal performance.

When performing a gas valve replacement, field technicians rely on the 100110223 for its exact fitment and redundant valve seats, which comply with stringent safety protocols. This component integrates seamlessly with the Electronic Integrated Control Module found in many Lochinvar and A.O. Smith units, supporting microprocessor-based timing and flame monitoring. By maintaining accurate air-gas mixture ratios, this valve helps sustain the 85% thermal efficiency typically required in modern hydronic and domestic hot water installations.

• Large Scale Compatibility: Features a high-capacity 1.25-inch inlet and outlet for superior flow management in commercial gas valves.
• Enhanced System Safety: Built-in redundant seats ensure a positive seal, preventing hazardous gas accumulation.
• Precision Combustion: Acts as a natural gas regulator, maintaining steady pressure to optimize the burner's efficiency.
• Rugged OEM Construction: Designed to withstand the high-temperature environments of professional boiler rooms.

Common Questions

Is the 100110223 compatible with Liquid Propane (LP)?
No, this specific part number is strictly for natural gas applications. Converting this valve for LP use is not recommended; always utilize the manufacturer-specified LP gas valve for safety.

Does this gas valve include a built-in regulator?
Yes, this model features an integrated low gas pressure regulator designed to maintain a consistent output to the burner regardless of minor fluctuations in the supply line.

Can I use this as a universal 1.25" gas valve?
This is an A.O. Smith OEM repair part. While it fits 1.25" piping, it should only be installed in specific models where the internal electrical and pressure requirements match the unit's original factory specifications.
