Pneumatic Segment Ball Valve


Segment Ball Valve




Coosai wafer type segment Ball valve combines the advantage of globe control valve with the efficiency of a rotary ball valve which satisfied the needs for throttle and shut off of flow within automatic process industry.The segment ball in V-notch design has strong cutting force and self-cleaning function.With the segment ball quarter turning the passage area changes in ectorial shape.Leading to the precise control of the flow , it is the ideal valve for most paper and pulp process application,Low CV value precise control is available by special V-notch on DN25 Segment ball.



Design Feature




Core

· Specially designed V-notch ball provides strong cutting stress and tight sealing.

· 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.

· Well ground notched ball surface ensures small operating torque and tight seal, especially for metal seated segment valve.

Body

· Integral body design ensures smooth flow, easy assembly and smaller shell leakage possibility.

· Both wafer and flange connection are available.

Stem

· The stem is finely ground to match the actuator excellently, which prevents rocking motion and potential failure of the segmented valve.

· Close-fit spline or pin-key are available for stem-core connection to provide reliable transmission without motion lost or dead band.

Seat

· Metal, RTFE or Devlon are available for seat options.

· 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.

FEATURES

1. Precise contouring of the V-notch provides excellent control characteristics for an extensive variety of flow applications.

2. Easy to change seats,means low cost for valve repairs.

3. Heavy duty construction with unrestricted sreaight through flow path gives high Capacity.

4. Superior trunnion bearing technology is engineered for excellent abrasion resistance.

5. Rugged self-adjusting metal seated option is ideally suited for high temperature applications or slurries.

6. Excellent sealing capacity-Class V Standard

7. Splined connection between the shaft and ball ensures precise control and low hysteresis.

8. Shearing action between ball and seal promotes smooth ,non-clogging operation-perfect for fiber or slurry applications.

9. Spring loaded seat maintains constant contact with the ball,giving enhanced sealing performance.
