Nordyne 904081 Valve

The Nordyne 904081 is a commercial-grade 24V gas valve engineered for precision fuel regulation in residential and light commercial forced-air furnaces. Built as a direct replacement for Honeywell VR8205 series controls (including VR8205M2443 and VR8205S2288), this dual automatic valve combination ensures safe burner operation through redundant safety shutoff. The 1/2" NPT straight-through body maintains consistent flow rates of approximately 150,000 BTUH, making it a drop-in solution for Miller, Intertherm, and Frigidaire furnace gas trains. It features a slow-opening characteristic typical of the 624775 gas valve, which prevents delayed ignition bangs and stabilizes the combustion envelope. This kit is pre-configured for natural gas with an LP conversion kit included for propane field adjustments. Operating on a 0.5A current draw, the integrated servo regulator effectively maintains a constant 3.5" W.C. outlet pressure, mitigating supply fluctuations common in high-demand heating cycles.

• Direct Cross-Reference: Fits a wide range of OEM part numbers including 6247750, VR8205S2262, and VR8205S2353.
• High-Stability Regulation: Adjustable servo regulator (2.5" to 3.5" W.C. for NG) provides stable manifold pressure for efficient heat exchanger performance.
• Reliable Cold-Weather Starts: Rated for ambient temperatures down to -40?F, ensuring dependable operation in unconditioned mechanical rooms.
• Contractor-Ready Hardware: Includes the 1/2" NPT valve, required barbed fittings, and a specific conversion orifice for propane applications.

What is the manifold pressure setting?
The valve is factory-set to 3.5" W.C. for natural gas but is field-adjustable between 3.0" and 5.0" W.C. depending on the specific furnace data plate requirements.

Can I use this for hot surface ignition (HSI) systems?
Yes, the Nordyne 904081 is designed for direct ignition systems including HSI and Spark ignition, drawing the standard 24VAC control voltage from the integrated furnace board.

Is this a slow-opening or fast-opening valve?
This model typically features a slow-opening design to allow for a soft light-off, reducing mechanical stress on the burner assembly.
