Description
This NIBCO wafer type butterfly valve is provided with undercut discs for actuation purposes only. The valve is specifically designed for low pressure (100 psi bubble-tight) on/off or modulating applications to be used in conjunction with pneumatic or electric actuators. This NIBCO wafer type butterfly valve is provided with undercut discs for actuation purposes only. The valve is specifically designed for low pressure (100 psi bubble-tight) on/off or modulating applications to be used in conjunction with pneumatic or electric actuators. This NIBCO ductile iron butterfly valve features a unique molded-in Buna-N seat liner with ductile iron, electro nickel plated disc, recommended for most water applications. The internal stem/disc geometric 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.
