The invention relates to a thermalactuator (1, 1 ') for a temperature-dependent movement of an element (22)of a valve, wherein a lengthchange of the thermalactuator (1, 1') depend on a surrounding temperature.Furthermore, the invention relates to a valve with such an actuator and the use of such a valve for controlling a fluid flow. It is envisaged that the actuator (1, 1 ') is made of a temperature dependingmaterial by means of an additive manufacturing method. L'invention concerne un actionneur thermique (1, 1') pour un mouvement dépendant de la température d'un élément (22) d'une vanne, dans lequel actionneur un changement de longueur de l'actionneur thermique (1, 1') dépend d'une température environnante. L'invention concerne également une vanne avec un tel actionneur et l'utilisation d'une telle vanne pour commander un écoulement de fluide. Il est envisagé que l'actionneur (1, 1') est réalisé en un matériau dépendant de la température à l'aide d'un procédé de fabrication additive.
