Design Feature

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.
