The Segment Ball Valve is specifically designed for flow control and can also function effectively as a shut-off valve. The segment ball features a notched port that generates strong shear force, enabling it to handle media containing fibers and particles with ease. This makes the valve an excellent choice for general control applications in industries like pulp and paper processing or for flows with similar fibrous or particulate content.

A V-port ball valve design incorporates either a V-shaped ball or a V-shaped seat. This configuration allows for precise opening and closing, offering a flow characteristic closer to linear. During operation, the small end of the "V" opens first, providing stable and controlled flow, particularly in the initial stages. To withstand the higher velocities often associated with such applications, these valves are constructed with robust materials and design, ensuring durability and reliable performance.
