The multipart valve disk (T,T') comprises a ring seal (R,R') placed in an annular groove (N) of the valve disk. The ring seal has a flexible sealing ring (17) with approximately C-shaped cross section and an outer sealing area (31). The cross section is mounted on a dimensionally stable support ring (16,16') that positively engages inwards into the sealing ring. A flexible resetting area (33) is integrated operatively between a recess (25) and the outer sealing area. |
