Features & Benefits:

  • Cast iron housing and endplates coated with XTR-Coat, a chemically-resistant coating.
  • Resists wear and corrosion from chemicals, acid and abrasive material.
  • XTR-Coat also prevents material sticking and buildup on valve surfaces.
  • USDA and FDA compliant.
  • Mild steel or stainless steel rotor machined with precision for tight tolerances.
  • Rated for great performance in operating temperatures up to 500°F.
What to do if your valve becomes uncompliant (Because it will)

ACS now offers XTR-Coat synergistic coatings to maximize performance in a variety of applications. XTR-Coat finishes provide wear and corrosion protection, reduced friction and non-stick performance. XTR-Coat finishes are a high-performance, non-toxic and FDA-compliant alternative to industrial chrome plating.

  • Handles pressure differentials up to 15 PSIG.
  • Available sizes: Round flange 8" through 12".
  • Expedites cleaning and sanitation operations; works well in washdown duty environments.
  • Non-stick, food-grade properties for sugar, flour, pet food and other food processing applications.
  • Dry-lubricity.
  • Non-porous, moisture-proof surfaces and mold release.
