Features & Benefits:

  • Available in 3 heights, from 16 ½” to 25”; and 3 flange diameters from 8" to 12".
  • This ACS Valves Pre-fit Performance™ Series valve enables simple and fast drop-in replacement of Carter Day® type CI rotary valves.
  • Large housing barrel enables 3-times more material throughput (CFR) than conventional valve housings with same flange opening.
  • 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.
  • Easily manages pressure differentials up to 15 PSIG.
  • Excellent performance in high-temperature applications up to 500°F.
  • Cast iron housing.
  • 8-vane rotor, complete with beveled tips and sides.
  • Unique shaft seal design results in lowered maintenance and downtime costs.
  • Round flanges aid material flow, improve cleaning.

Options:

  • 304 or 316 cast stainless steel valve housing.
  • Interior coatings: hard chrome, tungsten, and nickel.
  • Rotor types: closed-end, shallow-pocket, adjustable-tip, and Teflon®-coated.
  • Adjustable rotor tip types: EPDM rubber, polyurethane, hardened steel, stainless steel, and bronze.
