Ball Valves are so-named because their closing mechanism is ball-shaped.
When the ball is rotated so the hole is perpendicular to the flow openings of the valve body, the flow of fluid stops. If the hole through the ball is the same size as the pipe it is controlling, the valve is called a "full-port" ball valve. The ball in most water valves is made of stainless steel, and it rotates in a neoprene liner for smooth operation. Ball valves have fewer moving parts than gate valves and are considered more reliable. Most ball valves are the quick-acting type, meaning they require only a 90-degree turn to either completely open or close the valve. Some ball valves also contain a swing check located within the ball to give the valve a check valve feature.
Ball valves are available in IPS and sweat styles. They're also available for PVC.
