  • Rotary-valve design provides shearing action between the V-notch ball and the seat, promoting a smooth, non-clogging operation.
  • Straight-through flow design provides high capacity for fluids.
  • With a single-seat design, torque is lower than typical trunnion design valves, for ease of operation and reduced actuator cost.
  • Two seat designs:<ul><li>Laminated seat provides ASME/FCI 70-2 class IV shut-off and withstands tough operating conditions.</li><li>Thick (solid) seat for high-velocity and abrasive or erosive service.</li></ul>
  • Segmented, V-notched ball features high rangeability and smooth throttling action.
  • Choice of full and reduced port, providing the right flow capacity for every application at low cost.
  • Machined ISO 5211 top mounting flange (VA series only).
  • Heavy-duty, stainless steel shaft for high strength and rigidity.
  • Multiple, adjustable ring packing allows easy adjustment without valve disassembly or actuator removal.
  • Shaft bearings assure a durability, smooth and easy valve operation.
  • Positive alignment of split body.
  • The spline connection minimizes the backlash of shaft and disk. It results excellent control performance.
