The AMERICAN Series 2500 Ductile Iron 250 psig AWWA Resilient Wedge Gate Valve is designed for use in drinking water, sewage and fire protection systems as well as irrigation and backflow control systems. The Series 2500 Resilient Wedge Gate Valve is furnished in configurations that are UL Listed and FM Approved.
Two thrust washers are used. One is located above and one is located below the thrust collar. These thrust washers provide easy operation.
The ductile iron body, bonnet and wedge provide strength, durability and a pressure rating that meets or exceeds the requirements of AWWA C515. The tensile strength of ductile iron is more than twice that of cast iron. This added strength makes the Series 2500 more durable and allows it to be rated at 250 psig. This strength and higher pressure rating is provided in a compact, lightweight and easy-to-handle ductile iron valve.
The Series 2500 valve is epoxy coated on the interior and the exterior. The fusion-bonded epoxy coating is applied prior to assembly. The bolt holes and body-to-bonnet flange surfaces are fully coated.
The body-to-bonnet seals incorporate pressure-energized o-rings which reduces the need for excessive bolt loading required by designs that use flat gaskets. The gaskets are typically reusable, which reduces downtime during any needed repair.
The Series 2500 Ductile Iron OS&Y Resilient Wedge Gate Valve has these standard features:

Also available in 4"–12" class 250 raised face, per ASME B16.1, class 250 for cast iron flanges
Valves 2"-12" in size shall be of a resilient wedge design. The valve shall have a cold water rated working pressure of 250 psig. All cast ferrous components shall be ductile iron and shall be manufactured in compliance with the latest edition of ANSI/AWWA C515. The valve shall also be UL Listed and FM Approved in applicable configurations. The valve design shall be lightweight, easy to handle, and constructed with wall thickness as defined in Table 2 of ANSI/AWWA C515. Heavy wall and/or cast gray-iron bodies are not acceptable. The valve shall have a smooth and oversize waterway and have the marking “D.I.” or “Ductile Iron” and the designation C515 cast on the body. The valve wedge shall be constructed of ductile iron and provided with protective wedge guide covers in sizes 4"-12". All wedges 3" and smaller shall be constructed of bronze. All wedges shall be encapsulated with EPDM rubber. The valve shall be Certified to NSF 61-G, or NSF 372, as applicable.
Valve stems shall be constructed of bronze (or optional stainless steel) and supported by a ductile iron yoke and follower. Stems shall be sealed by packing which is held in place by a bronze gland. Packing shall be easily replaced and/or adjusted in the field.
All exterior valve body bolting shall be Type 304 stainless steel and shall be provided with hexagonal heads, with dimensions conforming to ANSI B18.2.1. Metric size and/or socket head cap screws or bolts, are not allowed. All body gaskets shall be of the pressure energized O-ring style design.
All internal and external ferrous surfaces of the valve body and bonnet shall have a fusion-bonded epoxy coating, complying with ANSI/AWWA C550. The coating shall be electro-statically applied prior to assembly.
All valves shall be the AMERICAN Series 2500 Resilient Wedge Gate Valve.
