The ball stop-cock has a housing with a rotatable closure ball (2) which contains a throttle mechanism (7, 13) which can be adjusted by means of a separate actuator (6) through an adjusting spindle (5) which extends through the hollow shaft (3). The throttle device has a throttle plate (10) which interacts with one of the two through-flow openings (11) of the ball and which can be displaced independently of the ball. |
