NIBCO’s grooved UL/FM butterfly valves are lightweight and install-ready. Their compact size makes installation easier in confined spaces, with a durable fused corrosion-resistant nylon coating, NIBCO notes. The valves feature a pressure rating of up to 350 psi, a re-engineered gear operator and a redesigned body for enhanced performance. The double- lipped EPDM encapsulated disc assures a bubble-tight seal and a lower torque gear operator requires less force to operate. Available in sizes ranging from 2 1/2” to 10.”
