F = Fast opening\n S = Slow opening\n\nOPERATION PRINCIPLE Safety valves type of supply\n 0 = Independent\n 1 = Simultaneous\nM2N combined gas valve comprises two class A automatic safety valves, direct-\nacting, electrically operated. Coils voltage\n 7 = 230 V AC\nAt rest, both safety valves are closed; thus gas cannot flow beyond chamber ①.\nWhen energized, the coils open and release the gas flow from chamber ① to\nchamber ② for safety valve V1 (from chamber ② to chamber ③ for V2).\nWhen de-energized, each safety valve closes within 0.2 s.
