Ball Valve Gate Valve
A ball valve is a form of quarter turn valve which uses a hollow perforated and pivoting ball called a floating ball to control flow through it.
Ball valve gate valve. When it s in the highest position water can flow freely. Gate valves have either rising stems which enable you to tell visually if they are open or closed although not as clearly as the lever on a ball. One advantage of a manually actuated ball valve over a gate valve is the handle position makes the position of the ball easy to see. Gate valves offer users significantly more control over the flow and pressure of the water than ball valves but do not afford users the option of an immediate stop of flow.
Ball valves are actuated manually and also by electric and pneumatic actuators as parts of flow control systems. Ball valves are designed with a ball inside the valve.
