Utica-Dunkirk VG-003.05 Gas Valve

The Utica-Dunkirk VG-003.05 Gas Valve is a direct OEM replacement component engineered for precision fuel regulation in residential gas-fired boilers. This 24V 1/2" natural gas valve is factory-set for a 3.5" WC manifold pressure, ensuring optimal combustion efficiency and reliable ignition cycles. Designed for Utica and Dunkirk boiler systems, this valve features a standard 1/2" NPT inlet and outlet configuration, facilitating a seamless drop-in installation for service technicians. The solenoid-operated mechanism provides consistent gas flow modulation, preventing short-cycling and maintaining flame stability under varying load conditions. For contractors performing a boiler gas valve replacement, the VG-003.05 offers the exact electrical and mechanical specs required to restore factory performance. Verify millivolt vs 24V compatibility and check your specific model number to ensure this HVAC gas control valve matches your unit's safety string requirements.

Key Technical Benefits

• Precise 3.5" WC Regulation: Maintains consistent natural gas delivery for peak thermal efficiency.
• OEM Compatibility: Specifically engineered for Utica-Dunkirk hydronic heating systems.
• Standard 1/2" NPT Ports: Simplifies field installation with standard piping connections.
• Reliable 24V Actuation: Integrates seamlessly with existing boiler control boards and thermostats.
• Compact Footprint: Fits within tight burner compartments common in older cast iron boilers.

Common Technical Questions

Can this natural gas valve be converted to Liquid Propane (LP)?
This specific model is calibrated for natural gas at 3.5" WC. Field conversion requires a specific LP spring kit and should only be performed by a licensed technician following manufacturer manifold pressure specifications.

What are the symptoms of a failing VG-003.05 gas valve?
Common indicators include delayed ignition, failure to prove flame, or an audible hum from the solenoid without gas flow. Always check for 24V at the gas valve terminals before condemning the part.

Is this a direct replacement for older Honeywell or White-Rodgers valves?
While functionally similar to many 24V redundant gas valves, the VG-003.05 is the designated OEM part for specific Utica and Dunkirk serial ranges. Always cross-reference the part number on the existing valve body.
