Abstract

A valve for the gastight interruption of a flow path is disclosed. A valve housing includes a first opening and a valve seat. A valve disk includes an inner disk portion, which is linearly movable relative to an outer disk portion so that, in a closed setting, a pressure differential acts substantially upon the movable inner disk portion, which is supported on the valve housing. The valve seat has a radially inward pointing first inner face and the outer disk portion has a radially outward pointing first outer face, wherein in the closed setting there exists a radial sealing contact with the first inner face. The outer disk portion has a radially inward pointing second inner face and the inner disk portion has a radially outward pointing second outer face, having a radially sealing contact with the second inner face.
