Features & Benefits:

  • 304 or 316 stainless steel valve housing, cast in North America, ensures superior housing solidification and metallurgy; eliminates pits and dimples where contaminants could accumulate.
  • Product contact surfaces of the housing, and all rotor surfaces, are a No. 4 finish.
  • Tool-less, single-step access to rotor and internal surfaces; simplifying cleaning, validation, and inspection.
  • RotorRail™ feature maintains rotor and endplate alignment during dis-assembly; ensures fast and accurate rotor and endplate re-alignment during re-assembly.
  • Run-Clean™ features include: angled surfaces, rounded edges, and factory-applied internal coatings to reduce material buildup in the housing during operation.
  • Available in 7 heights, from 10"H to 44"H; and 7 square-flange sizes from 6" to 30".
  • 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.
  • 8-vane rotor with beveled tips and sides.

Options:

  • 304, 304L, 316, 316L, or 2205 cast stainless steel valve housing.
  • No. 4 finish on internal product contact surfaces of housing, and all rotor surfaces.
  • Interior coatings: hard chrome, tungsten, and Teflon®.
  • Rotor types: closed-end, metering, shallow-pocket, adjustable-tip, and Teflon®-coated.
  • Adjustable rotor tip types: hardened steel, stainless steel, and bronze.
  • Shaft seal types: ACST-4™ glandless Teflon® shaft seal, and packing gland.
  • Valve housing vent ports.
  • Shaft seal and rotor pocket air purge.
  • 6-vane or 10-vane rotor.
  • Custom drive packages.
  • Application-specific accessories: blow-through adapter, shear plate deflector, surge hopper, motion speed switch assembly.
