Honeywell Gas solenoid valve VK4115VB2007U

This normally closed gas solenoid valve is designed for burner control and ignition systems, regulating gas flow to both pilot and main burner for heating, natural, and liquefied gas. It operates on 24 V, with a nominal inlet pressure of 25 mbar and ambient pressure of 1013 mbar. The valve has flanged connections with an inlet/outlet diameter of 18.6 mm, a pilot gas connection of 4 mm, and an output aperture of 2.8 mm. It features pressure control by a servo drive, an electric two-level regulator, throttle valve regulation, smooth ignition via Softlite technology, and 1:1 gas/air ratio regulation. The valve includes two electrical devices, a fine-mesh inlet filter (not intended for cleaning), an optional output filter, and a positive feedback system with pressure servo controller and pressure relief valve for stable output pressure. Gas consumption is indicated in cubic meters per hour, mounting is upright with holes at the bottom, and electrical connection is via connector or plug-in rectifier unit for standard DBI ignition systems.

When selecting a replacement gas solenoid valve of this type, ensure the flanged connection matches the existing pipe size (inlet/outlet), and verify the pilot gas connection and pressure sensor pipe diameters. The valve must be installed upright, secured through the mounting holes at the bottom. Electrical connections can be made via connector or plug-in rectifier unit; confirm the required operating voltage (24V optional) and whether an additional output filter is needed. If a side outlet is used, a flanged burner manifold is required.
