Fuel dumping valve for aircraft for fast emergency evacuation of fuel contained in the aircraft\s fuel tanks, consisting of a valve head seated in a valve seat and mechanical or hydraulic linkage for opening or closing the valve from the pilot\s seat. The valve may have hydrulically inflatable seals for completely sealing the valve against fuel leakage, and hydraulically controlled locking pins for holding the valve locked in the valve seat until deployment. An interlocking sequencing control mechanism is provided for retracting the locking pins, releasing the sealing pressure and activating the valve.
