Honeywell Gas solenoid valve VK4105N5016U

This gas solenoid valve has a classic body, uses flanged connections, and must be installed upright. It includes a built-in fine-mesh filter and a 2.8 mm diaphragm. This model offers a two-level electric regulator, alternative throttling valve control, Softlite soft-ignition system, 1:1 gas/air ratio regulation, and stepless regulation with amplification. The nominal inlet pressure is 25 mbar at 1013 mbar ambient pressure. The inlet and outlet diameter is 18.6 mm, the pressure sensor pipe is 0.5 inch, and the pilot gas connection is 4 mm. Available with closing-force variants b+j, b+c, and b+b and a variety of customizable options.

Gas solenoid valves of this type are selected by matching the flange connection size, the closing variant (b+j, b+c, b+b), and the electrical connection type to the existing system. Before ordering, measure the mounting dimensions and confirm whether a side gas outlet is present; if so, it can only be used with a flanged burner manifold. The valve body must be installed upright and secured via the mounting holes on the bottom.
