What Makes A Loose-Liner Butterfly Valve Suitable For Corrosive Applications?
The loose-liner butterfly valve features a replaceable, non-bonded liner that provides excellent chemical resistance and sealing performance, making it ideal for corrosive and abrasive media. Unlike bonded liners, the loose liner is not permanently affixed to the valve body, allowing for easier inspection, removal, and replacement when needed. This design reduces downtime and lowers maintenance costs, especially in industries like chemical processing, water treatment, and food production. The liner also acts as a gasket between the valve and flanges, simplifying installation and enhancing leak protection. Because the disc only contacts the liner—not the body—it prevents metal corrosion and improves service life. With versatility, ease of maintenance, and superior media compatibility, the loose-liner butterfly valve offers a practical and cost-effective solution for systems requiring frequent maintenance or exposure to harsh chemicals.
