Abstract
A rotary actuated valve choke or the like is remotely controlled by motor means fixedly mounted with respect to said valve to rotationally drive a stem thereof. Monitoring means measure the rotation of the motor and/or its associated drive train. The monitoring means convert the rotary motion to a more easily measurable linear motion to measure the valve setting and appropriately control the energization of the motor in response thereto.
