Abstract
A valve operator assembly is provided for a valve and includes a housing, an input member rotatably mounted with respect to the housing, and a transmission mechanism having a rotating screw provided with an outer thread and a translating nut surrounding and coaxial with the screw, the nut being provided with an inner thread, the transmission mechanism being adapted to convert rotation of the screw into axial translation of the nut. The input member is mounted on the rotating screw. The assembly further includes an outer translating sleeve radially disposed between the housing and the translating nut and adapted to be connected to the valve translating member of the valve. The outer translating sleeve is provided with an inner thread and is connected to the translating nut so as to slide relative to the housing when the rotating screw rotates.
