Engineered for high-output commercial and residential applications, the Lochinvar & A.O. Smith 100208601 Valve is a direct OEM replacement VR8303M4863 gas valve designed for precision fuel regulation. This standing pilot gas valve features a 3/4" x 3/4" NPT connection and is factory-calibrated for an outlet pressure of 1.8" WC. Whether you are servicing a Lochinvar Copper-Fin II boiler or an A.O. Smith water heater, this component ensures stable manifold pressure and reliable ignition sequences. It is technically equivalent to part numbers VAL2412 and VAL2412K, providing seamless compatibility for contractors maintaining HVAC systems. The 24V 50/60Hz solenoid design promotes consistent flow control, vital for maintaining thermal efficiency and combustion stability in demanding environments. This robust gas control valve is built to withstand rigorous cycling, making it a staple for professional technicians who prioritize rapid, drop-in repairs without the need for additional piping modifications.

• Universal Compatibility: Serves as an exact drop-in replacement for part numbers VAL2412, VAL2412K, and 100208604.
• Precision Pressure Control: Pre-set to 1.8" WC to match factory specifications for optimal burner performance.
• Standard Fitting: Features 3/4 inch NPT inlet and outlet ports for easy integration with existing manifold piping.
• Reliable Ignition: Designed specifically for standing pilot assemblies used in Lochinvar CH/CF 402 to 752 series units.

Is the 100208601 valve compatible with LP gas?
This specific model is calibrated for natural gas applications. Always check the orifice and regulator settings if converting fuel types, though this unit is typically utilized in its standard 1.8" WC natural gas configuration.

Which boiler models use the VR8303M4863 valve?
It is commonly found in Lochinvar Copper-Fin II® models, including the CH 402 through CH 752 and CF 402 through CF 752 series, as well as various high-capacity A.O. Smith commercial water heaters.

Does this valve include the pilot thermocouple?
No, this is the gas valve assembly only. Technicians should inspect the existing thermocouple and pilot tubing for wear during the installation of the new control.
