Honeywell VK4100Q2003 gas valve

The Honeywell VK4100Q2003B gas regulator is an integral part of the burner control and ignition system, which guarantees safe ignition, flame control and precise regulation of the gas flow for both the pilot and the main burner. This component includes the most reliable VK4100 Q 2003B gas valve and a high-tech ignition regulator that connects to it.

The Resideo VK4100Q 2003U valve stands out for its standard body and provides a wide range of settings, including:

• Precision pressure control using an innovative servo drive.
• Smooth and trouble-free ignition thanks to the unique SOFTLITE technology.
• Precise regulation of the gas and air mixture in an ideal 1:1 ratio.
• Electronic two-level regulator for maximum efficiency.
• Smooth and flexible regulation with the ability to adapt to different control methods.

The VK4100Q2003U gas regulator includes two electronic devices: one for precision control of the main valve and the other for continuous monitoring of its position.

This gas solenoid valve masterfully copes with various types of gases: heating, natural and liquefied.

General characteristics

The VK4100 Q 2003 gas solenoid valve combines all the safety and burner control functions in a superbly designed system. The inlet and outlet of the valve have a diameter of 18.6 millimeters and can be easily connected via flanges. There are various models of this valve with different levels of closing force, such as B+J, B+ C, B+ B, to meet a variety of needs.

A built-in fine-mesh filter is installed at the inlet of the Honeywell VK4100Q 2003B gas regulator, which serves as an additional safety element. An additional output filter can be installed if necessary. Special holes are provided on the lower part of the valve for a strong attachment to the installation.

There is a choice of different types of electrical connections, including connection to the ignition regulator via a special connector or the use of a plug-in rectifier unit for standard DBI ignition systems. In addition, 24 V operation options are available for maximum compatibility with various ignition regulators, with the exception of the S4565/S4585 series regulators, to meet the most stringent requirements.
