can ball valves be used for throttling
Ball valves can also be used for throttling and flow control? The answer is yes. Although the effect is not good, it still has the function of regulation and control.
Ball valves are evolved from Cock valves. It has the same action of rotating 90 degrees. The difference is that the cock is a sphere with a circular through-hole or passage passing through its axis. When the sphere rotates 90 degrees, it should be all spherical at the inlet and outlet to cut off the flow.
Ball valves can be closed tightly with only 90 degrees of rotation and a small moment of rotation. Fully equal inner chamber of the valve body provides a direct passage with little resistance to the medium. Ball valves are most suitable for direct opening and closing, but they can also be used for throttling and flow control. The main characteristics of the ball valve are compact structure, easy operation and maintenance, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for medium with poor working conditions, such as oxygen, hydrogen peroxide, methane, ethylene, resin and so on. Ball valve body can be integral or combined.
