Abstract
An actuator for a rotary valve preferably embodying a diaphragm motor operated by pressure fluid. A driving sleeve is reciprocated linearly by the diaphragm motor and within said sleeve is a rotatable shaft, which is axially aligned with the diaphragm motor and driven by a ball screw. A driven sleeve is fixed to said shaft and receives the stem of the valve. All parts are in linear alignment. Means are provided for limiting the extent of the linear movement of the parts.
