NIBCO LD-2000-3 Butterfly Valve with EPDM Liner, Bronze Disc 6 inch

Description

Product Overview

The NIBCO LD-2000-3 series represents a mature, high‑performance line of butterfly valves designed for demanding industrial and plumbing environments. Constructed from ductile iron, the valve body offers exceptional strength and resistance to corrosion, while the EPDM (ethylene propylene diene monomer) liner provides a flexible, chemical‑resistant sealing surface that eliminates leakage between the body and the disc. The aluminum bronze disc is precision‑machined to deliver smooth, reliable rotation and a tight shut‑off, even under high‑pressure conditions up to 200 psi. The lever‑lock handle gives operators a secure grip and precise control, reducing the effort required for opening and closing actions. With a 6‑inch nominal size, the valve fits standard pipe dimensions and is compatible with Class 125 and Class 150 flange ratings, making it a versatile choice for a wide range of pipework configurations. Additional specifications include a compact footprint of 8 × 12 × 6 inches, a weight of 25.41 lb, and a design that supports end‑of‑line service without the need for a downstream flange, simplifying installation and reducing overall system cost.

Usage

This butterfly valve excels in applications where reliable flow regulation, durability, and ease of maintenance are paramount. Typical use cases include water treatment plants, chemical processing facilities, HVAC systems, and municipal plumbing networks. The EPDM liner’s resistance to a broad spectrum of chemicals makes the valve suitable for handling aggressive fluids such as acids, alkalis, and solvents, while the ductile iron construction tolerates temperature fluctuations and mechanical stress. The valve’s 200 psi rating ensures safe operation in high‑pressure pipelines, and its geometric drive mechanism provides consistent torque transfer, reducing wear on the stem and bearings. Installation is straightforward thanks to the lug design and lever‑lock handle, which allow quick alignment with pipe flanges and rapid actuation during routine maintenance or emergency shutdowns. The valve’s compact size also makes it an ideal candidate for retrofit projects where space constraints are a concern.
