Honeywell Gas valve VK4115V1014B

The Honeywell VK4115V1014B is a gas valve designed for burner control and ignition systems, managing gas flow to both pilot and main burners. It operates at a nominal inlet pressure of 25 mbar and a maximum inlet pressure of 60 mbar, with a flow capacity of 3.2 m³/h. The valve features a flanged connection, side gas outlet, and an upright operating position. It includes a 2.8 mm diaphragm, a 4 mm pilot gas connection, and an inlet/outlet diameter of 18.6 mm. Electrical connection is via a connector or plug-in rectifier unit at 24V, with pressure measuring points on top and an input screen on the input side.

Parts of this type are selected by matching the connection thread or flange type, inlet and outlet diameters, and operating voltage to the existing system. The valve must be installed upright, and the gas type and pressure range must be compatible with the burner's requirements. Before ordering, verify the inlet and outlet orientations, pilot gas connection size, and electrical connection type to ensure compatibility with the burner manifold and ignition system.

Common failures include gas leakage past the valve seats, leading to unsafe operation or inability to shut off gas flow. Symptoms may include burner ignition failure, unstable flame, or gas odor. Check for proper electrical connection, diaphragm integrity, and pressure readings at the measuring points to diagnose issues.
