ARD Metal Seated Gate Valves AWWA C500

Rotating Disc Gate Valves

American R/D Series 50 Rotating Disc gate valves are a time proven product. This design has been manufactured and in service since 1908. These valves meet all requirements of AWWA C500, latest revision, and applicable ANSI, ASTM, and other industry standards. American R/D has more metal seated gate valve manufacturing and engineering experience than anyone in the industry.

  • 3” - 54” valves are rated at 250 psi and hydrostatically tested to 500 psi –ductile iron construction. Sizes 60” - 108” rated at 100 psi and tested at 200 psi
  • Rugged, full body thickness- more iron better resistance to corrosion
  • Selection of coatings — internally and externally — NSF-61 approved — meets AWWA C550, protects interior and exterior
  • All working parts are perfectly plain with no pockets to collect sediment or prevent free and easy movement
  • Internal parts cannot be assembled incorrectly or become disengaged while in service
  • Revolving discs, which seat in different positions each time the valve is operated, ensure maximum life in the most exacting conditions
  • Extra-wide disc and body seat ring faces provide a large seating area
  • Bypass valve equalizes pressure to ensure less stress on the discs when opening/closing the valve

Solid Wedge Gate Valves

American R/D 100 Line Solid Wedge valves meet all requirements of AWWA C500, latest revision, and applicable ANSI, ASTM, and other industry standards.

  • Valves available in NRS or OS&Y style
  • Adjustable packing gland with non-asbestos packing
  • Heavy duty full body wall thickness made in ductile iron
  • Available with flanged ends, MJ ends, grooved ends, or any combination
  • Full flow waterway
  • Selection of coatings — internally and externally — NSF-61 approved — meets AWWA C550, protects interior and exterior
  • Full guides engage with body guide to maintain parts in position: Valves 16" and larger use bronze wedge and body guides
  • Extra wide wedge and body seat ring faces provide a large seating area
  • Solid one piece tapered wedge assures excellent performance and prevents clogging
  • Corrosion resistant one piece stem made of high strength stainless steel
  • Close fitting stem to wedge engagement maintains component alignment
  • Bypass valve equalizes pressure to ensure less stress on the discs when opening/closing the valve
