Ball Valve - an overview | ScienceDirect Topics
Ball valves are used for both on/off and throttling service. Ball valves are similar to plug valves but use a ball-shaped seating element (Figure 4.56). They are quick-opening and require only a quarter-turn to open or close. They require manual or power operators in large sizes and at high operating pressures to overcome the operating torque.

Introduction to Milling Tools and Their Application
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
