The Segment Ball Valve is specifically designed for precise flow control while also being suitable for shut-off operations. Its segment ball features a notched port that generates strong shear force, allowing it to process media with fibers and particles effectively. This design makes it particularly suitable for pulp and paper applications, as well as other processes with similar flow characteristics. The valve's equal percentage flow characteristic ensures accurate and consistent performance. With its V-port design, which incorporates either a "V"-shaped ball or seat, the valve enables controlled opening and closing of the orifice, resulting in a flow profile that is closer to linear. The small end of the "V" engages first during operation, providing stable and gradual flow control. To manage high fluid velocities and reduce potential wear, the valve is constructed with durable materials and a robust design, ensuring long-term reliability.
