In a large heatable vacuum valve with sealing lips (70) in the form of diaphragm springs which, in the housing (80), are pressed onto an axial bearing surface (82) and, by virtue of the deformation which occurs during this process, are pressed radially onto the sealing surfaces (84) in the housing, the sealing lip (70) is composed of titanium or a titanium alloy. <IMAGE>
