1. A tank device (1) for storing a gaseous medium, the tank device comprising a valve device (2) and a tank (10), wherein the valve device (2) has a valve housing (20) with a longitudinal axis (11), in which valve housing (20) is formed an inner chamber (7), in which inner chamber (7) a main valve element (16) movable along the longitudinal axis (11) is arranged, which main valve element (16) interacts with a first valve seat (40) and thus forms a main valve (43), wherein a pilot valve element (18) movable along the longitudinal axis (11) is arranged coaxially with the main valve element (16), which pilot valve element (18) interacts with a second valve seat (41) in order to open and close an inlet opening (160) and thus forms a pilot valve (44), wherein the valve device (2) comprises a magnet coil (14), characterized in that the inlet opening (28) is arranged in the valve housing (20) coaxially with an outlet opening (30), whereby the gaseous medium can flow toward the valve device (2) or away therefrom axially with respect to the longitudinal axis (11), and the magnet coil (14) is arranged in the valve housing (20) and surrounds the main valve element (16) and the pilot valve element (18).
