A valve body (1) has, in a through flow passage (2), guide ribs (8) between which a spherical closure body (10) is arranged in a displaceably guided manner and, depending on the direction of flow of the medium, rests either against a seal (30) opposite to it or against stop faces (9). …Arranged between the seal (30) and the guide ribs (8) is a ring part (4), the internal bore (29) of which is slightly larger than the diameter of the spherical closure body (10), the partial length (l) of the internal bore (29) accounting for part of the total displacement travel (L) of the closure body (10). ……
