Construction Details
The Midland AWWA C508 Flanged Swing Check Valve uses a ductile iron 65-45-12 valve body, bonnet, disc, and clapper arm for durable waterworks service.
The internal assembly includes a 304 stainless steel hinge pin and disc seat bolts, bronze ASTM B62 seat components, an EPDM disc seat ring, NBR O-rings, and additional corrosion-resistant trim components.
The swing-check mechanism allows the disc to open with forward flow and swing toward the seat when flow reverses, helping prevent unwanted backflow through the piping system.

What material is the valve body?
The valve body is manufactured from ductile iron 65-45-12.
What material is the valve disc?
The swing disc is also manufactured from ductile iron 65-45-12.
What type of connections does the valve use?
The valve uses flanged inlet and outlet connections for installation into compatible flanged piping systems.
What is the pressure rating?
Midland specifies a 300 PSI pressure rating for this AWWA C508 flanged swing check valve family.
What material is used for the disc seat ring?
