Description
This NIBCO lug type butterfly valve provides bi-directional dead-end service without a downstream flange, and bubble-tight shutoff at 250 psi. The valve is ideal for commercial and some light industrial process applications, compressed air and vacuum services. This NIBCO ductile iron butterfly valve provides ease of operation with quarter-turn (90 degrees) open to close. The unique molded-in Buna-N seat liner with ductile iron disc provides good abrasion resistance properties and compatibility with solvents, oil, water and hydraulic fluid for compressed air and vacuum 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 butterfly valves for the most specified, versatile and economical valve option in commercial, mechanical and industrial applications.
