• The NIBCO® wafer type butterfly valve is classified as a fire protection control valve that are Underwriters Laboratories listed and Factory Mutual approved for bubble-tight shutoff at 250 PSI water working pressure. Wafer valves are recommended for quick installation and removal from piping.
• The NIBCO® ductile iron butterfly valve is designed specifically to meet the rigorous requirements of automatic sprinkler systems. The unique EPDM molded-in seat liner with ductile iron disc provides bubble-tight shutoff at rated pressure.

With the internal stem/disc geometric drive design there is no need for pins or bolts that may create leak paths or turbulence in the waterway. An extended neck allows for insulation up to 2 inches. Please refer to NIBCO technical data sheets, chemical resistance guides and catalogs for engineering and installation information.
