An electronic oxygen conserving device for controlling a flow of oxygen from an oxygen storage container to a user. When a conserve setting is selected, a flow of oxygen travels through an oxygen regulating valve that has an open state and a closed state. A temporary electrical charge or current is provided to the oxygen regulating valve during the initial inhalation of oxygen by an individual, opening the regulating valve opens to delivery oxygen to the user. The oxygen regulating valve remains open even after termination of the electric current. After a predetermined timed delivery dose or upon exhalation by the individual, a subsequent temporary electric charge or current is provided to oxygen regulating valve, closing the regulating valve closes to prevent delivery of oxygen to the user, thus conserving oxygen. The oxygen regulating valve remains closed even after termination of the subsequent electric current.
