Abstract

A seal support ring (1) for a valve (2), particularly a vacuum valve, which has a throughflow opening (3) and a basic body (4), which annularly surrounds the throughflow opening, and a fastener arrangement (5) for fastening the seal support ring to a valve housing (6) of the valve. The basic body has a first side (7) on which the seal support ring, in a mounted state on the valve housing, lies against the valve housing, and the seal support ring has a seal ring (8) made from an elastomer which, in its position on the basic body, surrounds the throughflow opening. A casing wall (9) is arranged on the basic body and at least partially surrounds the throughflow opening and, on a second side (10) of the basic body (4) opposite the first side, protrudes from the basic body and has a larger inside diameter than the seal ring.
