A shut-off valve for a pressurized-gas vessel includes a valve closing body which can perform stroke movements and is preloaded by the spring force of a closing spring against a valve seat. When the valve closing body is in a closed position, a connection of a valve inlet to a valve outlet is shut off. The shut-off valve includes an actuator arrangement for opening the valve closing body. The actuator arrangement interacts with an actuating element which is arranged spaced apart from and coaxial with respect to the valve closing body and which is movable by the actuator arrangement in the direction of the valve closing body. When the actuating element abuts against the valve closing body, an opening impulse can be generated.
