Lochinvar & A.O. Smith 100208612 Gas Valve

The Lochinvar and A.O. Smith 100208612 Gas Valve is a direct replacement 24V redundant intermittent pilot gas control engineered for high-recovery commercial water heaters and boilers. This 3/4" x 3/4" NPT valve is manufactured by Honeywell (model VR8304K4046) and is designed to handle high-capacity demands with a vertical or swing mounting orientation. It features a standard opening characteristic and includes a 1/4" NPT pressure tap for precise manifold pressure adjustments during combustion analysis. This component is functionally identical to VAL2928 and VAL2928K, ensuring seamless mechanical fitment and electrical compatibility with existing ignition modules. Built for rigorous HVACR applications, it manages gas flow safely with dual internal solenoids, providing reliable natural gas valve operation in systems requiring high British Thermal Unit output and consistent pilot ignition performance.

Key Benefits for Technicians:

• Universal Compatibility: Serves as the OEM replacement gas valve for a wide range of Lochinvar, A.O. Smith, and State Industries commercial units.
• Field Interchangeability: Direct cross-reference for VAL2928K and VR8304K4046, reducing truck stock requirements.
• Precise Pressure Regulation: Integrated regulator maintains consistent burner pressure for optimal combustion efficiency.
• Industrial Build Quality: Heavy-duty construction designed to withstand the high ambient temperatures found in commercial mechanical rooms.
• Standardized Wiring: 1/4" male quick-connect terminals allow for rapid integration with existing 24VAC control circuits.

Common Installation Questions:

What is the inlet/outlet size for the 100208612?
This valve features 3/4 inch NPT threads on both the inlet and outlet ports to accommodate high-flow gas lines.

Does this valve support LP gas conversions?
The 100208612 gas valve is typically setup for natural gas; however, it can be converted for Liquid Propane using the manufacturer-specified 393691 conversion kit.

Can this replace a VAL2928 exactly?
Yes, the 100208612 is the current manufacturer-authorized substitute for VAL2928 and VAL2928K, maintaining all original technical specifications and physical dimensions.
