Construction & Materials

  • Main Valve Body: Ductile Iron ASTM A536
  • Main Valve Bonnet: Ductile Iron ASTM A536
  • Disc Guide: Stainless Steel
  • Seat: Stainless Steel
  • Disc: Buna-N Rubber
  • Diaphragm: Nylon Reinforced Buna-N
  • Stem: Stainless Steel
  • Spring: Stainless Steel

Standard Features

  • Blue Epoxy Coated, FDA Approved
  • Pilot Assembly: "Wye" Type Strainer, Closing Speed Control (sizes 1 1/4" - 4"), Isolation Valves
  • Inlet Pressure Gauge
  • ANSI Class 150 Flanges
  • Copper Tubing and Brass Fittings

Caution: The recommended installation orientation for ACVs is horizontal, with the valve cover up. 6" and larger valves should only be installed horizontally, with the valve cover up, due to the difficulty of properly bleeding air out of the cover and performing maintenance on valves installed in the vertical orientation.
