ABSTRACT:
The disclosure provides an actuating mechanism for a rotatable ball valve unit wherein several axially extending pistons and cylinder units or bellows elements are mounted in the wall of the outer housing of the ball valve in angularly spaced relationship. Two diametrically opposed piston or bellows elements actuate the mechanism for axially shifting and then rotating the ball valve, while the remaining piston or bellows elements effect a displacement of the flow tube to maintain a seal carried by the flow tube in sealing engagement with the ball after its rotational movement has been accomplished. The desired delay of movement of the flow tube is accomplished through either varying the size of the bellows element or the spring constants of the springs opposing the actuating movement of the pistons, bellows elements or a combination of these.
