Product Details

Jacked Pneumatic Segment Ball Valve , V-port ball valve,V-Notch ball valve , pneumatic actuator V-ball valve

 

 

Coosai Jacked pneumatic segment Ball valve combines the advantage of globe control valve with the eccficiency of a rotary ball valve which satsfify 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 changesin ectorial shape.Leading to the precise control of the flowm,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

Body

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

· Both wafer and flange connection are available.

Ball

· 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.

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.

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.
