Ball valves offer very good shut-off capabilities. A simple quarter-turn (90°) completely opens or closes the valve. They are available in a wide range of body, seat and seal materials, suitable for a many different applications.
Ball valves also have a straight uninterrupted flow path which minimizes the pressure drop across the valve most notably in the full bore versions where the port through the ball has the same as the diameter of the pipe.
