ABSTRACT A ball valve is provided with a blocking mechanism which automatically blocks its control shaft in its respective rotary position between a closure position and an open position when the control movement takes place too rapidly, The blocking mechanism responds to the respective rotary position of an annular inertia body which is rotatably mounted on the ball valve housing and the rotary movement of which effected by spring action is initiated by the rotation of the control shaft and is retarded by its inertia. On adequately slow actuation of the control shaft the blocking mechanism does not become operative. When the actuation is too rapid and could lead to inadmissibly high pressure peaks the control shaft is blocked by the blocking mechanism.
