For a vacuum valve including a wall (1) with a valve opening (6) and a valve seat surrounding the valve opening (6) and a valve plate (7), during the closing of the vacuum valve starting from the open position of the valve plate (7), the valve plate (7) is moved over a main section of the closing path in a main closing direction (14) that is parallel to the valve plate (7) and parallel to the plane of the sealing surface (10) or the sealing ring of the valve seat, and is then moved, following the main section of the closing path, over a final section running at an angle to the valve plate (7) and at an angle to the plane of the sealing surface (10) or the sealing ring of the valve seat for guiding the valve plate (7) onto the valve seat. At least one guide element (15, 16) that guides the valve plate (7) over the end section of the closing path and that interacts with a guide element (17, 18) arranged on the valve plate (7) is arranged on the wall (1), and the valve plate (7) is guided over the final section of the closing path by guide surfaces (19, 20, 21, 22) that sit at an angle to the plane (45) of the sealing surface (10) or the sealing ring of the valve seat and of which at least one is arranged on a guide element (17, 18) of the valve plate (7) or on a guide element (15, 16) arranged on the wall (1).
