cast steel Stainless steel V port ball valve


 Design Features

V port  ball valve is a quarter-turn control valve. V type valve core is designed with a special V shape notch. This consequently contributes to strong shear force and precise flow control. Thus, TANA’s V-port ball valve is especially suitable for medium which contains fiber or solid particles.



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


  • 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.


  • 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.


  •  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.
