16"-60" Series 2500 Resilient Wedge Gate Valve With Flex-Ring Ends


AMERICAN’s 16"-60" Series 2500 ductile iron resilient wedge gate valves are suitable for use in potable water, sewage and fire protection systems.

AMERICAN’s 16"-60" Series 2500 ductile iron resilient wedge gate valves are suitable for use in potable water, sewage and fire protection systems. These valves have a rated working pressure of 250 psig with zero leakage. The waterway is clear and unobstructed.

The Flex-Ring design incorporates the following exclusive design features:

  • Positive joint restraint
  • No need for friction style restrainers
  • No point loading of pipe wall
  • No restraint hardware to corrode
  • Additional joint deflection compared to traditional pipe joints
  • Even distribution of pipeline thrust loads
  • Joint restraint hardware is protected inside the valve joint

Advantages Over Standard Butterfly Valve Designs

  • No disc in waterway to restrict flow or to increase pumping costs
  • Allows passage of pigging devices
  • Internal parts can be serviced without cutting valve out of pipeline
  • 250 psig rating provides for future pressure increases over the 150 psig pressure rating typically found on most butterfly valves

Advantages Over Standard Double-Disc Gate Valve Designs

  • Zero allowable leakage
  • Lower torque requirements to operate valve
  • 250 psig pressure rating compared to the 150 psig rating typically found on double-disc gate valves
  • Fusion bond epoxy-coated inside and out
  • Lighter total valve weight
  • Single-gate construction. Double-disc gate valves have multiple parts that can seize together.
  • Bypasses, rollers, tracks and scrapers are not needed.

Standard Features

  • 250 psig rating
  • Ductile iron construction
  • Triple O-Ring stem seals
  • NSF Certified coating
  • Thrust washers
  • Epoxy coating inside and out
  • Zero leakage
  • Optional gearing (Standard on 30" and larger)
  • Ductile iron wedge fully encapsulated with EPDM rubber
  • 16"-60" Flex-Ring boltless restrained joint
  • Cast flats on valve body so valve stands upright for storage or during installation
  • Bypass available at additional cost


  • Ductile Iron Construction
    The ductile iron body and bonnet provide superior strength and allow a pressure rating of 250 psig. The strength of ductile iron doubles that provided by gray iron. This added strength and higher pressure rating are provided in a compact, lighter design.
  • Triple O-Ring Stem Seals
    Sealing the lubrication chamber is a series of three O-Ring stem seals. The O-Rings help to isolate the lubrication chamber.
  • Epoxy Coating
    The 16"-60" Series 2500 valves are epoxy-coated both on the interior as well as the exterior of the valve. The coating is applied after the valve body is shot-blasted clean. The coating is applied to all ferrous surfaces so that even the bolt holes and body-to-bonnet flange surfaces are fully epoxy coated.
  • Lifting Devices, 16"-60"
    All 16"-60" valves are provided with integral lifting devices, which allow the valve to be handled without lifting it by the operating nut.
  • Thrust Washers
    Thrust washers are located above and below the stem collar to reduce operating input torque and assist in trouble-free operation of the valve.
  • No Flat Gaskets
    The stuffing box gasket and throat flange gasket are pressure-energized rubber O-Rings. This provides a seal without the need for excessive bolt loading as is required of flat gaskets.
