Honeywell VQ425MB 1004 Class "A" combined valve ignition system designed for controlling gas flow in high-capacity burners, atmospheric boilers, furnaces, and other systems. The valve's versatility allows for the installation of accessories such as a position indicator, pressure switch, air release valves, and bypass valves. Standard features include two safety valves: V1, which opens quickly, and V2, which can operate in multiple modes. In the standard version, the second valve (V2) comes with a throttle screw for quick opening with flow regulation. Optionally, V2 can be equipped with a slow opening device (with adjustable flow and opening time) or be set for quick opening without any regulating device.
