Ball valves are durable, reliable and securely shut off flow even after sitting idle for long periods of time. Because of this, they are frequently used as fluid and gas flow cut-off valves. Ball valves are also easy to operate. This plus their availability in a range of useful material options has led to their widespread use.
The principle of how Ball valves work is the same as any valve in that it controls the flow of water through it and has a handle to stop the flow when required. It is called this because of its ball or sphere closure unit inside the valve which opens and closes when the lever is turned, controlling flow. A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.
Ball Valves provide tight shut-off and predictable control. They have a high range of use due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves. Advantages include ease of operation and high flow, high pressure, and high temperature capabilities. Disadvantages include low cleanliness and an inability to handle slurries.
