Wafer Segment Ball Valve,A351 CF8,PN16,DN150
Wafer Segment Ball Valve belong to fixed ball valves and are also single seat sealed ball valves. Their regulating performance is the best among ball valves, and their flow characteristics are equal in percentage, with an adjustable ratio of 100:1. Its V-shaped notch has a shear effect between the metal valve seat, making it particularly suitable for media containing fibers, small solid particles, slurry, and other materials.
The Wafer Segment Ball Valve is primarily designed for flow control, and it can also be used for shut-off operation. The notched port on the segment ball contributes to strong shear stress to cut through media with fibers and particles. Consequently, this v-port segment valve is a good general control valve for most pulp and paper process applications, or similar flow contains fibers and particles.

Body
• Single-piece body prevents leaks caused by separate flanges or locking rings.
V-port Segment Ball:
• Specially designed V-notch ball provides strong cutting stress and tight sealing.
Well ground notched ball surface ensures small operating torque and tight seal,
especially for metal seated segment valve.
Seat
• Special seat design eliminates cavity between seat and valve body. This,
consequently, prevents media from jamming between seat and body, ensure reliable
sealing.
Seal Surface
• Nitriding/Tungsten Carbide/Satellite Alloy/Nickle Base Alloy plating are available for
abrasive media.
Stem
• Stem is finely grounded to match actuator excellently, which prevents rocking motion
and potential failure of the v-port segmented valve.
• Close-fit spline or pin-key are available for stem-segment ball connection to provide
reliable transmission without motion lost or dead band。
Application：
Pulp and Paper/Waste Water Treatment/ Food and Beverage/Chemical Plants/ Power Plants/ Steel Industry/Etc.
