Abstract:
A hermetically-sealed valve position indicator is provided with a valve control handwheel. Indicator includes a magnetic-coupling with a stationary mount for the valve control handwheel. During operation of valve control handwheel, its handwheel and shaft rotate along with a housing, housing cover, housing window, primary shaft, and drive gear about the actuator's central axis of rotation—clockwise or counterclockwise. Drive gear engages with drive train to rotate a needle across a dial face to indicate the position of a valve. Drive train includes two gears rotatably attached to a secondary shaft and an indicator gear attached to a back end of sleeve slid over a front portion of primary shaft. The needle is disposed on the front end of sleeve with the dial face positioned between the indicator gear and the needle.
