Description
AWWA Swing Check Valve Flanged
ASC Series 22FC AWWA Swing Check Valve is a flanged ductile iron check valve designed to automatically permit forward flow while helping prevent reverse flow in waterworks and compatible piping systems.
The valve features a ductile iron body, EPDM resilient disc seat ring, brass body seat, Class 125 flanged connections, and fusion-bonded epoxy coating. Series 22FC is rated for 300 PSI cold working pressure and conforms to AWWA C508.
