Introduction
Lined ball valves are ball valves with a corrosion-resistant lining on the inner surface of the valve body to achieve media isolation, used for the regulation and shut-off control of corrosive fluids.

Features
Durable Valve Body: Fluid only contacts the inner liner (compliant with ASTM F1545), isolating the metal valve body from the media and preventing chemical corrosion of the base material.
Integrated Sealing Surface and Liner: The ball passage and valve seat contact areas are both lined with the same material. When closed, the sealing pair forms contact between similar materials, reducing sealing mismatch caused by material differences.
Direct Actuator Mounting: The valve body top interface conforms to ISO 5211, allowing direct matching with pneumatic or electric actuators without additional connection structures.
Applications
Chemical Industry: Used for conveying and shutting off corrosive media such as acids, alkalis, and organic solvents, isolating metal from contact with the media.
Pharmaceutical Industry: Used for controlling corrosive or high-purity fluids, reducing the impact of metal ion precipitation on the media.
Water Treatment: Used for conveying water containing corrosive components, achieving pipeline regulation and isolation.
Environmental Engineering: Used for controlling waste liquids and corrosive discharge media, meeting system sealing and corrosion resistance requirements.
