Actuator for a valve device and valve device

Abstract

Actuator for a valve device, characterized in that it comprises: a coil housing (101); an electromagnetic coil (102) arranged in the coil housing, wherein the electromagnetic coil comprises a coil body (1021) and an aluminum wire wound on the coil body;and an embodiment component arranged axially through the coil body, wherein the embodiment component comprises a stationary iron core (103) and a movable iron core (104), wherein axial ends of the stationary iron core project out of the coil housing, wherein a radially inwardly recessed circumferential groove (1033) is formed on an outer circumferential wall of the stationary iron core to enlarge a receiving space between an inner circumferential wall of the coil housing and an outer circumferential wall of the stationary iron core at a corresponding position, wherein the coil housing is fixedly arranged in the circumferential groove at least in the axial direction, wherein an axially extending chamber is formed in the stationary iron core in which the movable iron core is arranged to be axially movable, and wherein the movable iron core is used to be connected to a valve core of the valve device.
