Honeywell VK4100D1025 gas valve

The Honeywell VK4100D1025U gas valve plays a key role in the burner control and ignition system, providing safe ignition, flame control and gas flow control for both the pilot and the main burner. This component includes the VK4100C1026 gas valve itself and a specialized ignition regulator that connects to it. The Resideo VK4100D1025B combined gas valve has a standard body and has a variety of functional settings, including: - Pressure regulation using a servo. - Regulation via the throttle valve. - Smooth ignition using SOFTLITE technology. - Regulation of the ratio of gas and air in a ratio of 1:1. - Electric two-level regulator. - Smooth regulation with amplification for various control methods. The VK4100D1025U gas solenoid valve is equipped with 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 gases: heating, natural and liquefied.
