An actuator for a valve element includes one base plate; one actuating element having a first end section, a second end section, and a sealing element on the first end section; one connecting element; and one SMA element having a U-shape including two parts substantially parallel to one another, a first end, a second end, and a middle section between the two parts. The actuating element is at least partially arranged on and connected to the base plate via the second end section. The connecting element is conductively connected to two points of the SMA element. A middle section of the SMA element is connected to the first end section of the actuating element so that a shortening of the SMA element causes a stroke of the sealing element.
