The invention relates to a tank device () for storing a gaseous medium, in particular hydrogen, comprising a valve device (), and a tank () and having a longitudinal axis (). The valve device () has a valve housing (), which is equipped with a pilot valve element () that can be moved along the longitudinal axis (), said pilot valve element () interacting with a first valve seat () in order to open and close a first outlet opening () and thus forming a pilot valve (). The valve device () can be actuated by means of a solenoid coil (), wherein a main valve element () is arranged in the valve housing (), said main valve element () interacting with a second valve seat () in order to open and close a second outlet opening () and thus forming a main valve (). The tank device () comprises a screw-in housing element (), wherein the valve device () is integrated into a neck region () of the tank () in a fixed manner by means of the screw-in housing element (). The valve device () is arranged in the tank () by means of a tank pressure and is in a closed position by means of a spring () when the solenoid coil () is deactivated.
