Shut-off device for at least partially blocking a fluid in a fluid line, comprising a blocking means which has a substantially cylindrical basic body and comprises a first end and a second end, wherein the blocking means can be positioned in the fluid line and, by rotation in a direction of rotation (A) about an axis of rotation (R), can be reversibly adjusted from a blocking position, in which no fluid can flow through the blocking means, into a throughflow position, in which fluid can flow through the blocking means. The blocking means comprises a first through-opening and a second through-opening, wherein the cross section of the first through-opening is smaller than the cross section of the second through-opening. |
