Honeywell VQ420MC1002 combi valve DN20

Honeywell VQ420MC1002 gas valves designed to regulate gaseous media in gas consumption systems that comply with international standards. Honeywell VQ420 MC 1002 CVI valves meet the requirements of EN 161. Honeywell VQ420MC1002 compact gas unit feature a direct flanged connection suitable for pipes ranging from 3/4″ to 2″.

The standard configuration of Honeywell VQ420MC1002 gas control unit includes two main valves: V1 and V2. The safety valve V1 always operates with rapid opening and closing.
