Flow is allowed when the hole that pierces the ball-shaped disc is in line with the inlet and outlet of the valve and is blocked when the ball is horizontally rotated 90 degrees, so that the hole of the ball is perpendicular to the opening of the valve. Ball valves can be referred to as complete port or minimized port (likewise known as regular or standard port) depending on the inner diameter or the valve. A ball valve is complete port if the hole of the ball is the exact same size as the inner diameter of the linking pipeline (resulting in lower friction) and described decreased port if the hole of the valve is one pipe size smaller sized than the pipe, resulting in less flow through the valve than through the shaft of the pipe.
