Abstract

A setting/operating device for operating a valve stem of a regulating valve, including: a sun gear that rotates upon reception of a rotational force from a drive motor; a fixed internal gear fixedly disposed to surround the sun gear and having teeth on an inner peripheral surface; a plurality of planetary gears disposed between the sun gear and the fixed internal gear that rotate in engagement with the sun gear and the fixed internal gear while revolving around the sun gear; a movable internal gear rotatably disposed coaxially with the fixed internal gear, having teeth that engage the planetary gear on an inner peripheral surface; and an output shaft coupled to the movable internal gear and configured to rotate the valve stem of the regulating valve, wherein the planetary gears have a torque limit structure that restricts power transmission when a torque exceeding a certain level is applied.
