Quarter turn ball valve segmented ball valve 3 inch ball valve

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.

A ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked. They are characterized by a long service life and provide a reliable sealing over the life span, even when the valve is not in use for a long time. As a result, they are more popular as a shut off valve then for example the gate valve. For a complete comparison. Moreover, they are more resistant against contaminated media than most other types of valves. In special versions, ball valves are also used as a control valve. This application is less common due to the relatively limited accuracy of controlling the flow rate in comparison with other types of control valves. However, the ball valve also offers some advantages here. For example, the valve still ensures a reliable sealing, even in the case of dirty media.

Ball valves are one of the most common valve types used in both residential plumbing and industrial processes. They are typically used for basic on/off service. For this reason they are referred to as shutoff valves, isolation valves, or stop valves. They are operated with a simple 90 degree turn (qurter-turn) of a sphere shaped obstructor or "ball". This ball has a hole through it to allow flow to pass through in one position, but stops the flow in the when rotated 90 degrees.
