Abstract

The valve operator assembly is provided for a valve and includes a housing, an input member rotatably mounted, and a transmission mechanism including a translating element and a rotating element connected to the input member, said transmission mechanism being adapted to convert applied rotation of the input member into axial translation of said translating element. The assembly further includes at least one locking mechanism radially interposed between the transmission mechanism and the housing, and provided with friction means in radial contact with the housing, and with at least one pre-stressing element acting on said friction means to maintain said radial contact. The pre-stressing element and the friction means cooperate together to lock the transmission mechanism with the housing in a static position of said assembly.
