The NIBCO® lug type butterfly valve provides bi-directional dead-end service without a downstream flange and Bubble tight shut-off at 250 psi. The valve performs well in isolation and throttling applications, commercial, some light industrial process and chemical applications that the liner compatibility will permit.

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 in. The unique molded-in EPDM seat liner with stainless steel disc is recommended for chemical applications the liner compatibility will permit. Please refer to NIBCO® technical data sheets, chemical resistance guides and catalogs for engineering and installation information.
