Honeywell VQ440MA1055 gas valve DN40

Honeywell VQ440MA1055 gas valves designed to regulate gaseous media in gas consumption systems that comply with international standards. Honeywell VQ440 MA 1055 CVI valves meet the requirements of EN 161. Honeywell VQ440MA1055 compact gas unit feature a direct flanged connection suitable for pipes ranging from 3/4″ to 2″.

The standard configuration of Honeywell VQ440MA1055 gas control unit includes two main valves: V1 and V2. The safety valve V1 always operates with rapid opening and closing. Meanwhile, the V2 valve can function either in a fast mode (with flow regulation) or in a slow mode (with both flow regulation and adjustable opening time).

At the main body (4) flange connections are provided to mount either an:

• internal by-pass valve to achieve high-low flame control
• internal or external pilot valve
• vent valve
• pressure switch (Min. or Max.)
• Valve Proving System (VPS) + pressure switch.
