NIBCO Inc. has expanded its large-diameter ductile iron butterfly valve offering with the introduction of a molded-in liner for its LD-2000 Series, now available in sizes 14 through 36 inches. The enhanced design improves sealing integrity and consistency while reducing field installation challenges, enabling reliable full-pressure, end-of-line service in demanding applications.
Built on NIBCO’s proven industry-leading design, the LD-2000 Series is trusted across commercial mechanical construction and general utility service. Designed for commercial and industrial applications, these valves provide bi-directional and dead-end isolation with pressure ratings up to 200 psi.
The addition of the molded-in liner helps reduce common field installation challenges while delivering dependable, long-term performance. Combined with NIBCO’s durable construction, the updated design supports efficient installation and reliable operation.
“With the addition of the molded-in liner, we’re making installation easier while improving performance in the field,” said Craig Miller, Senior Product Manager-Valves, NIBCO. “This enhancement reflects our continued commitment to delivering reliable, high-quality valve solutions for commercial and industrial systems.”
The LD-2000 Series features a ductile iron, epoxy-coated body designed for enhanced corrosion resistance, an extended neck that accommodates up to 2 inches of insulation, and a one-piece, high-strength stem engineered for precise disc positioning and reliable performance.
