ASTM A216 WCB Segment Ball Valve, 16 IN, CL150, V Port, RF

Product Name: Carbon Steel V Port Segment Ball Valve
Body Material: ASTM A216 WCB
Size: DN400, 16 Inch
Pressure: PN16, Class 150 LB
End Connections: RF
Operation: Bare Shaft

The Segment Ball Valve is engineered for precise flow control and can also be used for shut-off applications. Its distinctive notched port design provides enhanced shear stress, making it ideal for cutting through media with fibers and particles. This valve is well-suited for pulp and paper process applications, as well as other processes where flow contains fibers or particles. Additionally, the valve features a V-shaped ball or seat, creating a controlled opening and closing process that delivers closer to linear flow characteristics. In the closed position, the small end of the "V" opens first, ensuring stable flow control during initial stages. This design allows for high-performance control but requires a robust construction to handle higher fluid velocities without damage.
