Honeywell VQ425MA1038 gas valve DN25

Honeywell VQ425MA 1038 Class “A” gas solenoid valves designed to control gas flow in high-capacity burners, atmospheric boilers, furnaces, and other gas-consuming systems. Honeywell VQ425 MA 1038 gas valve’s versatility allows for the installation of accessories such as a valve position indicator, pressure switch, air release valves, and bypass valves.

Honeywell VQ425MA1038 CVI valve meet EN 161 standards and are suitable for regulating gaseous media in systems adhering to international standards. Honeywell VQ425MA1038 gas control unit come with flanged pipe connections ranging from 1/2″ to 2″. Standard features include two safety valves: V1, which always opens quickly, and V2, which can operate in either fast or slow modes.

• As standard, the second valve (V2) supplied with a throttle screw (quick opening with flow control).
