The NIBCO® cast iron butterfly valve provides ease of operation with quarter-turn (90 degrees) open to close. The valve features a Buna-N encapsulated ductile iron disc. The internal stem/disc splined drive design eliminates the 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. Choose NIBCO® butterfly valves for the most specified, versatile and economical valves option in commercial, mechanical and industrial applications. NIBCO® butterfly valves are backed by the NIBCO 5-year 125% limited warranty.
