Utica-Dunkirk VG-008.04 Valve

The Utica-Dunkirk VG-008.04 Gas Valve is an essential OEM replacement component designed for precision fuel regulation in residential and light commercial boiler systems. Engineered for high-reliability intermittent pilot ignition sequences, this 24V gas valve features a 3/4-inch x 3/4-inch NPT configuration (often supplied with reducer bushings for 1/2-inch or 3/8-inch adaptability) to ensure a secure, leak-free connection with the manifold. As a redundant pilot valve, it incorporates dual internal solenoids for an added layer of safety, preventing gas flow in the event of a flame sensing failure. This unit is calibrated for natural gas applications with a standard 3.5" WC output, maintaining consistent manifold pressure for clean combustion and optimal thermal efficiency. For technicians servicing Utica boilers or Dunkirk heating systems, this genuine replacement gas valve restores factory-spec performance, preventing the common "no-heat" calls associated with shorted coils or mechanical sticking in legacy combination gas valves.

• OEM Compatibility: Specifically designed to match the electrical and flow requirements of Utica and Dunkirk boiler chassis, ensuring drop-in replacement without field modifications.
• Redundant Safety Logic: Features a dual-solenoid design that provides two points of shut-off for maximum protection during the combustion cycle.
• Versatile Porting: The 3/4" pipe size entry/exit points allow for high-volume flow, while standard reducer bushings facilitate integration with smaller 1/2" gas lines.
• Reliable Ignition: Built for intermittent pilot systems, ensuring the pilot burner only draws fuel during the call for heat, improving overall seasonal efficiency.
• Durable Brass Construction: The heavy-duty housing resists corrosion and thermal stress, maintaining seat integrity over thousands of cycles.

Is this valve a direct replacement for natural gas or propane systems?
This model is factory-configured for natural gas with a standard 3.5" water column setting. If your application requires Liquid Propane (LP), you must use a manufacturer-approved LP conversion kit to change the regulator spring and orifices for higher manifold pressures.

How do I diagnose if the VG-008.04 valve is faulty?
Confirm that the control board is delivering 24VAC to the PV (pilot valve) and MV (main valve) terminals. If voltage is present at the coil but the valve fails to click or release gas to the pilot assembly, the internal coil is likely open or shorted. Use a multimeter to check for resistance across the terminals; an "OL" reading indicates a total coil failure.

Can I use this gas valve in a standing pilot system?
No, the VG-008.04 is engineered for electronic intermittent ignition. It is not designed to support the continuous thermocouples or thermopiles found in older standing pilot furnaces or boilers.
