The Series 2500 Ductile Iron 250 p.s.i.g. 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. Ductile Iron Construction
The ductile iron body, bonnet and wedge provide strength and a pressure rating that meets or exceeds the requirements of AWWA C515. Strength more than doubles that provided by cast gray iron designs, and the pressure rating is 250 p.s.i.g. All this strength and higher pressure rating is provided in a compact, lightweight and easy-to-handle ductile iron valve.
Fusion-Bonded Epoxy
The Series 2500 valve is fully epoxy coated on the interior and the exterior. The fusion-bonded coating is applied prior to assembly so that even the bolt holes and body-to-bonnet flange surfaces are fully epoxy coated.
Triple O-Ring Stem Seals
This valve features triple O-Ring stem seals. Two O-Rings are located above, and one O-Ring is located below the thrust collar. The lower two O-Rings provide a permanently sealed lubrication chamber that will make the valve easier to operate over a longer period of time. The upper O-Ring ensures that sand, dirt or grit cannot enter the valve to cause damage to the lower O-Rings. This is especially important for buried and sewage service applications.
Thrust Washers
Two thrust washers are used. One is located above, and one is located below the thrust collar. These thrust washers ensure easy operation at all times.
No Flat Gaskets
The body-to-bonnet and bonnet-to-bonnet cover seals are pressure-energized O-Rings. This eliminates the need for excessive bolt loading, which is required by designs that use flat gaskets. The O-Rings are reusable, which eliminates downtime during any needed repair.
