Abstract: A method for controlling a valve including a direct current motor acting upon an aperture adjusting part (3) against the force of elastic means (11) biasing the aperture adjusting part towards a zero flow rest position, comprising the steps of: selecting a desired valve aperture; determining a time interval (T.sub.a) as a function of the desired valve aperture; supplying the motor with a first constant current of a sufficient value for rotating the motor, during the mentioned time interval; supplying the motor with a second constant low value current thereafter until a next valve aperture is selected, this low value current being sufficient to hold the motor in its position against the force of the elastic means.
