ACS Valves Rotary Valves for Bulk Material Processing

Rotary Valves: Airlock

MD Series

MD Series Rotary Valve

Features & Benefits:

  • Available in 7 heights, from 7 3/8"H to 23 1/2"H; and 7 flange diameters from 4" to 16".
  • 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 15 PSIG; with super-duty series up to 22 PSIG.
  • Excellent performance in high-temperature applications up to 750°F.
  • Cast iron housing.
  • 8-vane rotor with beveled tips and sides.

Options:

  • 304 or 316 cast stainless steel valve housing.
  • RotorRail™ feature provides tool-less access to rotor and internal surfaces; speeds cleaning and inspection; ensures fast, accurate rotor and endplate re-alignment.
  • No. 4 finish on internal product contact surfaces of housing, and all rotor surfaces.
  • Interior coatings: hard chrome, tungsten, nickel, and epoxy.
  • Rotor types: closed-end, metering, shallow-pocket, adjustable-tip, and Teflon®-coated.
  • Adjustable rotor tip types: EPDM rubber, polyurethane, 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, 10-vane, or 12-vane rotor.
  • Custom drive packages.
  • Application-specific accessories: blow-through adapter, shear plate deflector, surge hopper, motion speed switch assembly.
