The NIBCO® wafer type butterfly valve provides bubble-tight shutoff at 200 PSI. The wafer valve is ideal for commercial and some light industrial process applications including HVAC and vacuum services, in addition to hot and cold water.

The NIBCO® ductile iron butterfly valve provides ease of operation with quarter-turn (90 degrees) open to close. The valve's unique molded-in Buna-N seat liner with CF8M stainless steel disc is recommended for most applications. 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. Choose NIBCO® ductile iron butterfly valves for the most specified, versatile and economical valve option in commercial, mechanical and industrial applications. NIBCO® butterfly valves are backed by the NIBCO 5-year 125% limited warranty.
