412 Resilient Wedge Gate Valves with Flanged Joint Ends OS Y
4"-12" Resilient Wedge Gate Valves with Flanged Joint Ends - OS & Y

Product Description

The AMERICAN Series 3500 Ductile Iron 350 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 3500 Resilient Wedge Gate Valve is furnished in configurations that are UL Listed and FM Approved.

Thrust Washers

Two thrust washers are used. One is located above and one is located below the thrust collar. These thrust washers provide easy operation.

Ductile Iron Construction

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 3500 more durable and allows it to be rated at 350 psig. This strength and higher pressure rating is provided in a compact, lightweight and easy-to-handle ductile iron valve.

Fusion-Bonded Epoxy

The Series 3500 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.

O-ring Style Gaskets

The body-to-bonnet and stuffing box gaskets utilize pressure-energized O-rings. This reduces the need for excessive bolt loading, which is required by designs that use flat gaskets. The O-rings are reusable, which reduces downtime during any needed repair.
