The invention relates to a solenoid valve (), in particular a shut-off valve for hydrogen tank systems, comprising a reciprocatingly movable magnetic armature () which is or can be coupled to a reciprocatingly movable valve element (), the magnetic armature () being preloaded in the direction of the valve element () by means of a spring (), the solenoid valve further comprising an annular solenoid coil () for acting on the magnetic armature (), the solenoid coil () surrounding the magnetic armature () in portions. According to the invention, the magnetic armature () has a portion () designed as a plunger armature and a portion () designed as a flat armature, the portion () designed as a plunger armature delimiting a pressure chamber () within the solenoid coil (), which pressure chamber is connected pneumatically, preferably via a choke (), to a control chamber () which can be relieved by opening a control valve () which can also be actuated by means of the solenoid coil (). The invention also relates to a hydrogen tank system comprising a solenoid valve () according to the invention.
