NIBCO® ductile iron butterfly valves provide ease of operation with quarter-turn (90 degrees) open to close. The EPDM cartridge liner with ductile iron, electro nickel plated disc is recommended for most water applications. An extended neck allows for insulation up to 2 inches.
The NIBCO® lug type butterfly valves provides bubble-tight shutoff at 150 psi and bi-directional dead-end service without a downstream flange to 150 psi. The valve is recommended for commercial and some light industrial process applications, in addition to HVAC and hot and cold potable water.
