Honeywell Gas valve VK4115VE1013U

The Honeywell VK4115VE1013U is a gas valve designed for burner control and ignition systems, ensuring safe ignition, flame control, and gas flow regulation for pilot and main burners. It operates at 24V and features a standard housing with a side gas outlet. The valve has an inlet/outlet diameter of 18.6 mm and a pilot gas connection diameter of 4 mm, with a nominal inlet pressure of 25 mbar. It incorporates a positive feedback system and offers smooth regulation with amplification. This valve is compatible with Ferroli ECONCEPT TECH 25 A, 25 C, 35 A, and 35 C models.

When selecting a gas valve of this type, ensure the operating voltage, inlet/outlet diameters, and pilot gas connection size match the existing system. Verify the nominal inlet pressure and the orientation of the gas outlet (side or other) to fit the burner manifold. Check the electrical connection type, such as connector or plug-in rectifier unit, to ensure compatibility with the ignition control. The valve's housing type and design features, like positive feedback, should align with the burner's requirements.

Common failures in gas valves of this kind include sticking or leaking due to debris or wear, leading to inconsistent gas flow or failure to open/close properly. Symptoms may include burner ignition failure, flame instability, or gas pressure fluctuations. Check for proper electrical connections and voltage supply, and inspect the valve for physical damage or blockage. If the valve does not respond to control signals, it may need replacement.
