In order to reduce the friction of a dry-running solenoid valve (1) with a valve housing (2), in which an electric coil (3) and a magnet armature (5) are arranged, and with a valve element (8) which can be actuated by the magnet armature (5) in an axial actuating direction for opening and closing the solenoid valve (1), in which the coil (3) generates a magnetic flux which, when the solenoid valve (1) is actuated, flows via a magnetically conductive valve housing outer wall (2c) of the valve housing (2) to the magnet armature (5), it is provided according to the invention that a magnetically conductive flux element (12) be provided in the valve housing (2) and introduce at least 80%, preferably at least 90%, and particularly preferably 100%, of the magnetic flux flowing over the valve housing outer wall (2c) into an armature end face (5B), facing the coil (3), of the magnet armature (5).
