Injection valve (62) comprising an injector body (38) with a central longitudinal axis (L) and a first cavity (7). The injection valve (62) also comprises a valve body (4), a valve needle (10), an armature (12) and an actuation unit (4). The valve body (4) comprises a second cavity (8). The valve needle (10) is axially movable in the second cavity (8) and comprises a first radial surface (30). The armature (12) is decoupled from the valve needle (10) and is axially movable at least partially within the first cavity (7) and comprises a radial armature surface (32). The first radial surface (30) and the radial armature surface (32) are facing each other and feature a contact area (50) of a predetermined size if the valve needle (10) is in a predetermined axial position. The actuator unit (40) is operable to magnetically actuate the armature (12) to move axially.
