Abstract: An electromagnetic positioner for positioning the drive arm of a servovalve or the like, comprising an armature extending between laterally spaced pairs of vertically disposed and vertically spaced coils for pivotal movement in a plane which includes the axes of said coils, a drive arm assembly comprising a flexure tube secured to the base or lower pole of the positioner, and extending upwardly to a position above the level of the armature, and an adapter secured at its lower end to the armature and its upper end to the upper ends of the flexure tube and drive arm so that the pivot point of the armature is adjacent but above the center of rotation of the drive arm. Also provided is a null adjusting arrangement in which the driven parts are located partly in the body of the positioner and partly in the body of the pilot valve, thereby freeing space in the positioner and reducing the height thereof.
