摘要

The sealing element (7) has a base body (73) with a sealing surface (70), where the base body comprises a first sealing area and a second sealing area spaced from the first sealing area. A first thickness of the sealing element to the first sealing area is different from a second thickness on the second sealing area, where the first sealing area is separated from the second sealing area by a shoulder (76). A rear side (75) is provided on the base body perpendicular to the longitudinal axis (X-X) of the sealing element. An independent claim is included for a gas valve.
