Utica-Dunkirk 240004794 Gas Valve
The Utica-Dunkirk 240004794 Gas Valve is an OEM standard-replacement Honeywell VK8115F1134U gas control designed specifically for high-efficiency hydronic boiler systems and atmospheric furnaces. Engineered as a Combined Valve and Ignition (CVI) system, this component integrates both the gas regulation and ignition control interface into a single, compact block. It features a 24V, 50/60Hz operation with a fast-opening delivery mechanism to ensure immediate ignition once the safety string is proven. With a 105mm body length and an 18.6mm input diameter, it fits seamlessly into the manifold assemblies of late-model Utica and Dunkirk boilers, promoting stable fuel-to-air ratios and consistent BTU output.
For service technicians, the VK8115F1134U is built with a rugged die-cast aluminum housing and features a side-outlet configuration for streamlined field installation. This furnace gas valve replacement utilizes advanced servo pressure regulation to maintain steady manifold pressure even under varying inlet supply conditions, preventing nuisance lockouts and ensuring HVAC part compatibility across multiple residential platforms. Whether you are performing a mid-season repair or a system overhaul, this valve provides the precision required for modern gas boiler troubleshooting and long-term heating reliability.
Key Benefits for the Contractor- OEM Precision: Direct replacement for Utica-Dunkirk part 240004794, ensuring correct flange alignment and electrical terminal matching without field modification.
- CVI Integration: Simplified Honeywell CVI valve architecture supports direct mounting of S4565 or S4575 ignition modules, reducing wiring complexity and potential points of failure.
- Fast-Opening Operation: Engineered for quick ignition cycles, minimizing delay from the call for heat to burner stabilization.
- Enhanced Regulation: Internal servo pressure regulator compensates for supply fluctuations, protecting the burner assembly and optimizing combustion efficiency.
- Compact Footprint: The 105mm body length is ideal for tight vestibules in modern wall-hung and floor-mount boiler units.
Is the VK8115F1134U interchangeable with other VK8115 series valves?
While they share the same base platform, specific versions vary by opening speed (fast vs. slow), pressure range (mbar/\" WC), and outlet orientation. Always verify the individual suffix code and voltage requirements before installation.
What are the signs of a failing 240004794 gas valve?
Technicians typically look for a "clicking" sound without main burner ignition, a fault code at the boiler control indicating a failed gas valve circuit, or manifold pressures that drift outside of the appliance nameplate specifications.
Does this valve support both Natural Gas and Propane?
This valve is typically shipped for Natural Gas. To utilize it in LP applications, a conversion kit must be installed per the manufacturer's instruction manual to adjust the regulator spring and orifice settings.
This item is not eligible for free shipping.
