The NIBCO® ductile iron butterfly valve features a unique EPDM molded-in seat liner with ductile iron, electro nickel plated disc, recommended for most water applications. With the internal stem/disc geometric drive design eliminates 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.
The NIBCO® lug 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.
