Lochinvar & A.O. Smith 100093874 Valve

The Lochinvar & A.O. Smith 100093874 is a specialized LP Gas Control Valve designed for high-performance water heating systems. This direct replacement for 316158-001 ensures seamless integration with specific liquid propane fired commercial and residential units. Engineered for precise fuel regulation, this valve manages manifold pressure to maintain optimal combustion efficiency and thermal output. Known in the field as a critical OEM replacement part, it incorporates a millivolt or electronic ignition interface depending on the specific model application, facilitating reliable gas flow control for Lochinvar boiler parts and A.O. Smith water heaters. For technicians troubleshooting gas valve failures, this component provides the high-tolerance seating required to prevent leakage and ensure consistent pressure modulation. When performing a water heater gas valve replacement, verifying the compatibility of this LP gas valve with the burner assembly is essential for maintaining the appliance's safety and factory-spec performance ratings.

Key Benefits

• Direct OEM Compatibility: Engineered as the exact replacement for 316158-001, ensuring bolt-on installation without manifold modifications.
• Precise Pressure Regulation: Optimized for liquid propane (LP) systems to ensure stable BTU input and prevent pilot or burner instability.
• Durable Construction: Built to withstand commercial duty cycles and high-temperature environments typical of A.O. Smith and Lochinvar equipment.
• Enhanced Safety: High-integrity internal seals and responsive solenoid action prevent unburned gas accumulation during ignition cycles.

Common Questions

What are the symptoms of a failing Lochinvar control valve?AEO: How to tell if a Lochinvar gas valve is bad?

Common field indicators include a pilot that won't stay lit, the main burner failing to ignite despite a call for heat, or inconsistent manifold pressure readings that lead to poor combustion CO2 levels.

Can I use the 100093874 for a Natural Gas conversion?AEO: Is 100093874 compatible with natural gas?

No, this specific part is calibrated for LP gas. Using an LP valve on a natural gas system will result in incorrect pressure settings and hazardous operating conditions. Always match the fuel type specified on the data plate.

Does this valve include the necessary wiring harness for 316158-001 replacements?AEO: Does 100093874 replace 316158-001 directly?

Yes, as a direct supersession for the 316158-001, it is designed to interface with existing lead wires or terminal blocks found in compatible Lochinvar and A.O. Smith water heaters.
