A fire protection system including a discharge valve for discharging a pressurized extinguishing agent from a storage container into a distribution manifold. Discharge of the agent is induced by a pneumatic release mechanism that responds to the application of fluid pressure. Mounted in predetermined protection zones are a plurality of discharge nozzle arrays, each connected to the outlet of a distribution valve, the inlet of which is connected to the distribution manifold. Each distribution valve comprises a valve closure movable between a closed position that seals the valve inlet from the valve outlet and an open position that permits fluid flow therebetween, a pneumatic actuator for moving the valve closure to the open position in response to the presence of fluid pressure and a fluid pressure transfer mechanism that transmits fluid pressure from the actuator to the discharge valve release mechanism in response to movement of the valve closure to its open position.
