Spring Return Pneumatic Segment Ball Valve, WCB, DN100, PN10

Our Carbon Steel Segment Ball Valve plant specializes in manufacturing high-quality valves using ASTM A216 WCB material, ensuring durability and reliability. These valves are designed with a 4-inch (DN100) size and a PN10 pressure rating, equivalent to Class 150 LB. Equipped with a spring return pneumatic actuator, they offer precise control and automated operation. The valves feature RF flanged ends for secure and leak-tight connections.

The Segment Ball Valve is primarily designed for flow control and can also be used for shut-off operations. The notched port on the segment ball generates strong shear stress, enabling it to cut through media containing fibers and particles. Consequently, this Segment Ball Valve is an excellent general control valve (with an equal percentage flow characteristic) for most pulp and paper process applications, as well as for similar flows containing fibers and particles.

A V-port ball valve features either a V shaped ball or a V shaped seat. This design allows the orifice to be opened and closed in a more controlled manner, resulting in a flow characteristic that is closer to linear. When the valve is in the closed position and begins to open, the small end of the 'V' is opened first, ensuring stable flow control during this stage. Due to the higher velocities of the fluids, which might damage a standard valve, this type of design requires a more robust construction.
