Floating ball valves, or spit body, ball valves are designed with a “floating” ball that is to say that the ball is held between two elastomeric seats.  The ball is driven through 90 degrees quarter turn by the shaft which connects into a machined slot on the top of the ball.

In this design the upstream line pressure is pushed against the elastomeric seats to creating a tight shut off.
