Features & Benefits:

  • 12-vane rotary valve and return-side vent port design significantly reduce air leakage and ensure optimal bulk density and material feed efficiency of hard-to-convey materials.
  • Steep-angled inlet flange aids material infeed; improves material flow performance.
  • Available in 2 heights, 16.14"H and 18.50"H; and 2 flange diameters, 8" to 10".
  • Valve housing cast in North America; ensures superior strength and solidification of housing's metallurgy.
  • CNC-machined components and housing provide precision tolerances; eliminates axial shaft movement, extends maintenance cycles.
  • Outboard bearing design protects bearings in high-temperature and high-PSIG applications; removes bearings from direct path of damaging contaminants.
  • Easily manages pressure differentials up to 20 PSIG.
  • Excellent performance in high-temperature applications up to 500°F.

Options:

  • 304 or 316 cast stainless steel valve housing.
  • No. 4 finish on all rotor surfaces.
  • Interior coating: hard chrome.
  • Adjustable rotor tips.
  • Custom drive packages.
  • Application-specific accessories: motion speed switch assembly.
