Operation: Electric Actuator

The Segment Ball Valve is primarily designed for flow control but can also be used for shut-off operations. The notched port on the segment ball generates strong shear stress, allowing it to cut through media containing fibers and particles. As a result, this valve is well-suited for general control applications with an equal percentage flow characteristic, making it ideal for pulp and paper processing or similar industries handling fiber-laden and particulate-rich flows.
A V-port ball valve features either a V-shaped ball or a V-shaped seat, enabling more precise modulation and a closer-to-linear flow characteristic. When the valve begins to open from the closed position, the small end of the 'V' opens first, ensuring stable flow control during the initial stage. Due to the higher fluid velocities involved, this design typically requires a more robust construction to withstand potential damage that might compromise standard valves.
