Flange Segment Ball Valve,CF8,150LB,6 Inch,RF End
FEATURES
1. Easy to change seats,means low cost for valve repairs.
2. Precise contouring of the V-notch provides excellent control characteristics for an extensive variety of flow applications.
3. Splined connection between the shaft and ball ensures precise control and low hysteresis.
4. Shearing action between ball and seal promotes smooth ,non-clogging operation-perfect for fiber or slurry applications.
5. Spring loaded seat maintains constant contact with the ball,giving enhanced sealing performance.
6. Heavy duty construction with unrestricted sreaight through flow path gives high Capacity.
7. Superior trunnion bearing technology is engineered for excellent abrasion resistance.
8. Rugged self-adjusting metal seated option is ideally suited for high temperature applications or slurries.
9. Excellent sealing capacity-Class V Standard
The Flange 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 Segment Ball Valve is a good general control valve (equal percentage flow character) for most pulp and paper process applications, or similar flow contains fibers and particles.

Features:
1. Body：
a) Integral body design offers greater rigidity against fluctuating pipe loads.
b) Eliminates the leak path associated with two piece body designs.
c) Both wafer and flange connection are available.
2. Core：
a) Specially designed V-notch ball provides strong cutting stress and tight sealing.
b) Hard chromium, nitriding, and HCOF treatments are all available for the ball surface treatment, improving hardness,
abrasion resistance, fatigue resistance, corrosion resistance and performance under high temperature.
c) Well ground notched ball surface ensures small operating torque and tight seal, especially for metal seated
segment valve.
3. Seat：
a) For valve rated under class 150, retainer is casted on valve body to eliminate any possible space between seat
ring and body for residue accumulation. Consequently, this ensures perfect seal。
b) Specialized spring design decreases valve torque while providing force for tight sealing.
c) Pressure energized seat design offers excellent sealing even at very low differential pressures.
4. Stem：
a) The stem is finely ground to match the actuator excellently, which prevents rocking motion and potential failure
of the segmented valve.
Application:
Pulp and Paper/Waste Water Treatment/ Food and
Beverage/Chemical Plants/ Power Plants/ Steel Industry/Etc
