A fire extinguishing system that is of the gas dispersion type is provided, whereby a given supply cylinder, controlled by a cylinder valve, is piped to a plurality of directional or line valves for delivery to various locations. Sensing devices are also provided for controlling the line valves and cylinder valves as are manual valve operators. A particularly novel cylinder valve is provided, whereby once the valve is opened, venting of one side of the piston prevents closing prior to discharge of fluid from the cylinder.
