A sealing body (10) is made in one piece of elastic material and comprises annular sealing portions (11-18) for effecting a seal axially between different chambers in the valve casing, as well as connecting portions (19a-25a, 19b, 20b, 24b) which connect the annular sealing portions (11-18) and are adapted to seal between complementary valve casing parts, e.g. between two casing halves. |
