Beschreibung
Zusammenfassung:	The invention relates to a shut-off valve (1) for a hydrogen tank system, comprising - a main valve (10) with a valve element (11) which is designed as a solenoid armature (12) at least partly or in some sections and which is acted upon by the spring force of a main valve spring (14) in the direction of a main valve seat (13), - a control valve (20) with a valve element (21) which is designed as a solenoid armature (22) at least partly or in some sections and which is acted upon by the spring force of a control valve spring (24) in the direction of a control valve seat (23), and - a solenoid coil (2) which is arranged between the main valve (10) and the control valve (20) for generating a magnetic force which acts on the two solenoid armatures (12, 22) so as to open same, wherein the valve element (11) of the main valve (10) is designed in multiple parts and comprises two parts (11.1, 112) which are coupled via a tension spring (15) such that the axial distance (a) between the parts (11.1, 11.2) is variable. The invention additionally relates to a hydrogen tank system comprising a shut-off valve (1) according to the invention.
