ASTM A351 CF8 Segment Ball Valves, DN100, PN16, Pneumatic

The ASTM A351 CF8 Segment Ball Valves Manufacturer produces high-quality segment ball valves. The ball valve features a stainless steel body made from ASTM A351 CF8 material, ensuring durability and corrosion resistance. These valves are available in DN100 (4 inches) size, operate at a pressure rating of PN16, and are classified at 150 LB. They come with raised face (RF) flanged ends for secure connections and are equipped with a pneumatic actuator for efficient and reliable operation.

Product Name: ASTM A351 CF8 Segment Ball Valve
Body Material: ASTM A351 CF8
Size: DN100, 4 Inch
Pressure: PN16, Class 150 LB
End Connection: RF
Operation: Pneumatic Actuator

The Segment Ball Valve is designed for precise flow control and can also perform shut-off operations. Featuring a notched port, the segment ball generates strong shear stress to efficiently cut through media with fibers and particles. This makes it an ideal choice for general control applications, particularly in industries such as pulp and paper, where fiber and particle-laden media are common.
The valve also features a V-port ball or seat design, which ensures more controlled opening and closing, providing a flow characteristic closer to linear. The unique 'V' shape allows the small end of the port to open first during the initial stage of operation, enabling stable flow control. Given the higher fluid velocities and the potential for damage, this design is built with a more robust construction than standard valves.
