Abstract
A vacuum valve, having a valve seat including a valve opening (axis (A)), and a first sealing surface around the valve opening and defines a first sealing plane (ES), having a valve disk with a second sealing surface corresponding to the first sealing surface and defining a second sealing plane (ET), additionally having a first coupling element, connected to the valve disk and comprising a receiving means and a drive unit coupled with the first coupling element and is configured to provide the valve disk adjustable from an open position to a closed position. The drive unit and the valve disk are configured to provide a fine control position, wherein the valve disk is tilted relative to the valve seat where ES and ET enclose a defined angle (α), and the seal abuts fully against one of the two sealing surfaces and in part against the other sealing surface.
