Brochure: 14" - 66" Series 2500 Resilient Wedge Gate Valves

AMERICAN’s 14"-48" 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.


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 14"-48" 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, 14"-48"
All 14"-48" 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.
