ABSTRACT:
A rotary plug valve actuator comprising a mounting bracket, a ball screw mechanism pivotably mounted to the mounting bracket and a lever pivotably mounted to the ball screw mechanism. The ball screw mechanism includes a ball screw shaft and a ball nut. The ball nut moves axially on the ball screw shaft when the ball screw shaft is rotated. The lever converts the axial movement of the ball nut to rotary motion. In that way, rotation of the ball screw shaft will in turn actuate the rotary plug valve. An associated rotary plug valve assembly and an associated method of actuating a rotary plug valve are also provided.
