CF3M Hard Seated Segment Ball Control Valve 90 Degree Flange End With 4-20mA Positioner

90 Degree Flange End Hard Seated Segment Ball Control Valve With 4-20mA Positioner

Segment ball valve description

TEKO Segment ball Control valve is a rotary shutoff valve with V- shaped gap in the core. Using it with valve positioner may realize ratio adjustment. It is widely used in industrial sectors such as petroleum, chemical, paper-making, metallurgy water treatment, and so on. It may regulate or cut off the media in pipeline. It has a big flow coefficient, booster ring at valve seat for adjusting sealing force load, so that can ensure tight seal.

Product features of segment ball valve

A. Movable spring -loaded valve seat structure prevents jamming or severing between ball core and valve seat to make the seal reliable and useful life long.

B. There is shearing action between V- shaped notch ball core and metal valve seat, so it is especially applicable to media containing fiber. micro solid materials, pulp, and so on.

C . When it is fully open, there will be a big flow capacity and small pressure loss and the medium will not deposit in the valve cavity.

D.The valve has precise adjustment and reliable position function. The flow characteristic is approximate equal percentage and the adjustable range is wide with largest adjustable ratio of 100: 1.

Main Parts

Body

• Integral body design ensures smooth flow, easy assembly and smaller shell leakage possibility.
• Both wafer and flange connection are available.

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.

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.
