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. 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

Benefits

• 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.
