The Honeywell VK4105G1013U gas regulator is a part of the burner control and ignition system that provides safe ignition, flame control and gas flow control for the pilot and/or main burner. This system includes the VK4105G 1013U gas valve itself and a special ignition regulator that is attached to it.
The Resideo VK4105 G 1013U gas valve has a standard housing and can be configured with various options, such as:
- Pressure regulation by means of a servo drive.
- Regulation by means of a throttle valve.
- Smooth ignition using the SOFTLITE system.
- Gas and air regulation with a ratio of 1:1.
- Electric two-level regulator.
- Smooth regulation with amplification for various types of control.
The Honeywell VK4105G1013 gas solenoid valve has two electrical devices: one for controlling the main valve and the other for controlling its position.
This gas solenoid valve can work with three types of gas: heating gas, natural gas and liquefied gas.

General provisions
The Honeywell VK4105G1013B gas valve combines all the safety and burner control functions in one reliable system. The inlet and outlet of the valve have a diameter of 18.6 millimeters and can be connected via flanges. There are different models of this valve with different levels of closing force: B + J, B + C, B + B.
At the inlet of the VK4105G 1013B gas regulator there is a built-in fine-mesh filter, which is not intended for cleaning. An additional output filter can be added if necessary. There are holes at the bottom of the valve for mounting to the installation.
There are variants of gas valves with side gas outlet for both the main and pilot burners. However, such a side outlet can only be used with a flanged burner manifold. In addition, there is a connection for pilot gas with a diameter of 4 mm at the outlet of the Hanivel VK4105 G 1013B gas regulator. It is also possible to install pressure measuring fittings using silicone tubes with a diameter of 4 or 6 mm.
It is worth noting that there is a choice of different types of electrical connections, such as connecting to the ignition regulator using a connector or using a plug-in rectifier unit for a standard DBI ignition system. In addition, it is possible to choose options for operation at a voltage of 24V for joint use with other ignition regulators, excluding regulators of the S4565/S4585 series.
The principle of operation
As for the principle of operation, VK4105G1013 gas regulators use a positive feedback system (the main valve automatically closes when there is no power supply or gas pressure is exceeded). The system includes a pressure servo controller and a pressure relief valve that work together. When the power supply is supplied, the gas passes through the servo controller and opens the main valve. The system then maintains a constant pressure by regulating the operation of the main valve. This ensures a stable output pressure, even with changes in the input pressure.
