The ball has a hole through it, by which the valve opens and closes
When the ball is positioned so that the hole runs the same direction as the passageway, the fluid simply flows through the hole, and the valve is open
However, when the ball is positioned so that the hole is perpendicular to the passageway, the fluid cannot pass through, and the valve is closed
The ball is controlled from outside the valve, often with a handle that is turned 90 degrees, or a quarter turn, back and forth to open and close the valve
