Abstract: A shutoff valve for hydrogen tank systems having at least one compressed gas container. The shutoff valve includes a main valve, and a control valve for controlling the main valve. The main valve has a reciprocating valve piston which interacts with a valve seat and delimits, at its end facing away from the valve seat, a control chamber which is connected to a storage volume of the compressed gas container via an inlet throttle and via an outlet throttle, connectable to a gas outlet depending on the switch position of the control valve. The main valve includes a solenoid using which an opening and/or holding force acting on the valve piston can be generated. A compressed gas container having the shutoff valve, and a hydrogen tank system comprising at least one compressed gas container and the shutoff valve, are also described.
