The NIBCO® cast iron sliding disc check valve is wafer style to fit between standard flanges. Wafer checks may be installed in horizontal positions (or vertical with flow moving up). Please refer to NIBCO® technical data sheets, chemical resistance guides and catalogs for engineering and installation information. Choose NIBCO® check valves for the most specified, versatile and economical valve option in commercial, mechanical and industrial applications.
