Abstract

Valve (1), in particular vacuum valve, having a passage opening (2) and a closure member (3), it being possible for the closure member (3) to be moved by a valve drive (4) of the valve (1) in a closing direction (5) from an open position, in which it releases the passage opening (2), into a closed position, in which it closes the passage opening (2), and in the reverse direction. The closure member (3) is arranged in the closed position between two valve seats (6, 7) which lie opposite one another and surround the passage opening (2), and a first closure member part (8) of the closure member (3) bears against a first of the valve seats (6) in the closed position and a second closure member part (9) bears against the second valve seat (7) in the closed position. The closure member parts (8, 9) are mounted such that they can be displaced relative to one another in the closing direction (5).
