The invention relates to a device for controlling a valve (1) between an opened position and a closed position, that includes a valve actuation organ (8), an elastic system (17, 20) for oscillating the actuation organ between two end positions, at least one electromagnet (14, 15) associated with a control unit (23) for attracting the actuation organ towards its end positions, wherein the control unit supplies power to the electromagnet for attracting the actuation organ into a first end position when the required energy amount is at most equal to a threshold and for allowing the actuation organ to move back to the other end position when this amount is higher than the threshold. The invention also relates to a control method.
