Abstract: Described herein are a system for providing oxygen to oxygen masks in an aircraft, and an associated method for regulating the oxygen flow in an efficient manner. The system has an oxygen tank, oxygen masks, first and second oxygen lines, and an electrically controllable valve. The valve is coupled to the oxygen tank and the two oxygen lines. The oxygen masks are coupled to the oxygen lines downstream of the valve to accommodate the transfer of oxygen from the oxygen tank via the valve. In a working state when an electrical signal is applied the valve produces a connection between the oxygen tank and the first oxygen line when required, and permanently prevents a connection between the oxygen tank and the second oxygen line. When in a rest state, the valve produces a permanent connection between the oxygen tank and the second oxygen line.
