Abstract: An actuation ball valve has an elongated knob which replaces prior art quarter turn valves. The knob comprises a thread that runs along a cylindrical portion of the knob, wherein the nut has a corresponding cut-out for the thread. This helps the knob move/slide in and out of the nut. The knob and nut are designed so that a specific distance can be covered in a quarter turn, as the valve moves from its horizontal (OFF) position to its vertical (ON) position. The knob and nut can be modified to travel various distances at different degrees of turn to actuate the system being controlled. The knob has a cut-out at the bottom which is used to insert one or more washers and a self-threading screw to stop the rotation of the knob with respect to the nut at it moves out in the OFF position.
