Beschreibung
Zusammenfassung:	A system, in certain embodiments, includes a gate valve (38) including a gate disposed within a valve body (40). The gate valve also includes a motorized ball screw actuator (48) having an actuating rod assembly (80) directly coupled to the gate. The motorized ball screw actuator is configured to linearly actuate the actuating rod assembly to drive the gate (68) between an open position and a closed position Dans certains modes de réalisation de l'invention, un système comprend un robinet-vanne qui comprend lui-même un opercule disposé dans un corps de robinet-vanne. Le robinet-vanne comprend aussi un actionneur motorisé à vis à billes ayant un ensemble tige d'actionnement accouplé directement à l'opercule. L'actionneur motorisé à vis à billes est configuré pour actionner linéairement l'ensemble tige d'actionnement afin d'entraîner l'opercule entre une position ouverte et une position fermée.
