An electromechanical valve assembly for controlling oxygen flow from a compressed oxygen source in an aircraft includes: a valve housing, an inlet, an outlet, a passageway allowing flow of oxygen from the inlet to the outlet, a spring-biased conical poppet movable within the passageway; a spring-biased pressure regulating piston engagable with the conical poppet to maintain it in an open position, a push rod engagable with the conical poppet to maintain it in a closed position, and a movable seat in the passageway that engages the conical poppet to regulate gas flow through the passageway. Actuation of an electric motor assembly to cause the seat to move upward results in closing of the valve assembly and shutting off of the oxygen flow. Actuation of the motor assembly to cause the seat to move downward results in opening of the valve assembly and regulation of the oxygen flow.
