CI Series

ACS Valves CI Series rotary valve | AST Canada

The CI Series rotary valves are also available in sanitary 304 or 316 cast stainless steel models. Sanitary CI Series models also offer the ACS RotorRail quick-clean feature.

Features & Benefits:

  • Available in 10 heights, from 10″H to 44″H; and 10 square-flange sizes from 6″ to 26″.
  • 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, 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, nickel, and epoxy.
  • Rotor types: closed-end, metering, shallow-pocket, adjustable-tip, and Teflon®-coated.
  • Adjustable rotor tip types: EPDM rubber, polyurethane, mild steel, 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.

MD Series

ACS Valves MD Series rotary valve | AST Canada

For long-term savings, ACS designed this valve to reduce total lifecycle maintenance requirements. The MD Series housings are cast in North America and CNC-machined to precise tolerances, eliminating axial shaft movement, seal leakage, and shortened bearing life.

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.

ACS multi-port valve | AST Canada

Multi-Port Valve

The first ever Multi-Port for high volume applications

A transformation of trough-style feeders, the Multi-Port rotary valve provides high capacity in a compact design with separated airlock compartments. You won’t find another one like it on the market.

12in. Multi-port Series Valve Datasheet

Features & Benefits:

  • Trough-style openings can be designed to fit dust collectors, hoppers, bins, silos and screw conveyors.
  • Higher capacity with a smaller overall height for tight space engineered solutions.
  • Tighter clearances enable NFPA compliance despite larger capacity outputs (since NFPA clearances can be challenging in larger airlocks).
  • With independent drives, issues or a breakdown in one compartment can be contained and allow other compartments to continue operating.
  • Common parts in a unique housing mean no special maintenance requirements. Spare parts are readily available (whereas spares for larger airlocks can have a longer lead time).
  • Separate airlock compartments allow for intermittent feeds — two, three or four rotors can run simultaneously or independently for multi-line feeds.
  • More compact design than other valves of its kind, which reduces stack-up in silos and dust collectors.
  • Direct drives in each compartment allow for independent operation.

Options:

  • Use to break up large pneumatic conveying systems into smaller, more manageable systems.
  • Can be equipped with one elongated blow-through adapter to feed one system or multiple blow-through adapters for different line feeds.
  • Equip with one large pressure blower package or several smaller ones for multiple systems.
