  • The seat ring design self-centers, self-laps, and dynamically aligns with V-notch ball, giving superior cycle life.
  • No special orientation, precision clamping, or repetitive centering of V-notch ball and seat ring is required when tightening the retainer, promoting accurate alignment and easy assembly.
  • Precise contouring of V-notch ball provides a modified equal percentage flow characteristic.
  • Unrestricted, straight-through, flow design provides greater capacity than many conventional globe and rotary eccentric plug valves.
  • Integral valve flanges mate with many different classes of pipeline flanges, satisfying a variety of piping requirements.
  • The V-notch ball cams into and out of the seat minimizing contact with the seat ring for reduced wear and friction.
