Abstract
The valve according to the invention in intended, in particular, for high-pressure gas containers containing up to 300 bar. It comprises a shut-off element which is hold on its valve seat under the action of a compression spring and of the gas pressure. In order that the high closing pressure can be overcome with relatively little force, a piston whose top surface has a larger diameter than the diameter of the valve seat is provided on the actuating side. This top surface is situated in a pressure space which can be connected to the interior of the gas container via a pressure-balance passage by means of an electromagnetically actuable closing element.
