Abstract
A vacuum valve includes a valve housing (1) having a first housing part (1a) and a second housing part (1b), between which a ring-shaped housing seal (3b) is arranged, and a closure member (9) which is adjustable between an open position in which the vacuum valve is open and a closed position in which the vacuum valve is closed. The housing seal (3b) is mounted on a ring-shaped carrier (3a). Additionally on the carrier (3a) radially inside the housing seal (3b) is mounted a ring-shaped seat seal (3c) against which the closure member (9) is pressed with the closure member (9) in the closed position, wherein the seat seal (3c) abuts against a sealing face of the valve housing (1).
