APCO CSD Slanting Disc Check Valves

APCO CSD slanting disc check valve's rugged design features excellent flow characteristics, minimal head loss and maximum slam resistance for clean municipal water, industrial water, and other industrial clean liquid applications.

Its unique two-piece body and slanted disc orientation provide superior flow characteristics (lowest head loss) when compared to other check valve designs. The angled body seat expands cross sectional flow by 40%. Valves six inches or larger have an access cover for internal inspection on each body half. Free open/controlled closure or slow open/controlled closure device add-ons available.
