  • Page 4: Safety Instructions

    Any device modification requires prior written consent of the manufacturer. 1.2 Range of application AUMA SA/SAR multi-turn actuators are designed for the operation of industrial valves, e.g. globe valves, gate valves, butterfly valves, and ball valves. Other applications require explicit (written) confirmation by the manufacturer.
