ABSTRACT:
A high thrust operator for gate valves employs an inverted satellite roller screw assembly driven by an internally threaded cylinder carried within a bearing case. The cylinder is sized to provide a relief plenum within the case into which the roller screw assembly can be over extended to expose tool engagement flats for attachment and release of a mating stem in the valve gate actuator.
