Abstract
A vacuum valve with a seating ring having a generally rectangular cross section. With respect to rectangular edges lying diametrically opposite one another, radii of curvature are arranged in these edges, which radii of curvature come into sealing engagement with sealing seats arranged lying opposite one another on the housing side and the disk side. The sealing surfaces on the sealing seats have approximately the same cone angle. The sealing ring is easy to produce, has a small rolling path and there is no danger of damage to the valve seats by the sealing ring.
