Abstract

A sealing element of a valve, e.g., a gas valve, for controlling a medium includes a base body having a sealing surface, the sealing surface either (i) being inclined in relation to a center axis of the sealing element or (ii) having at least one inclined area. In addition, a valve seat support of the valve for controlling a medium includes: a first ring-shaped valve seat in a first valve seat plane; a second ring-shaped valve seat in a second valve seat plane; and a passage aperture situated between the first valve seat and the second valve seat, the first and second valve seat planes being perpendicular to a center axis of the valve seat support.
