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.
  • 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.
  • Product contact surfaces of the housing, and all rotor surfaces, are a No. 4 finish.
  • Available in 4 heights, from 12" to 25"; and 4 flange diameters from 6" to 12".
  • 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.
  • 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.
