A double flanged lined butterfly valve with gear operation is a highly durable valve designed for controlling the flow of corrosive, abrasive, or high-temperature fluids in large pipelines. The double flanged design features flanges on both sides of the valve body, ensuring a secure and leak-proof connection to the pipeline, making it suitable for high-pressure and demanding applications. The internal lining, typically made from materials such as PTFE or other resistant compounds, offers exceptional protection against corrosive and abrasive media, enhancing the valve’s lifespan. The gear-operated mechanism provides smooth, precise control, especially in large valves or systems where manual operation may be difficult. Commonly used in industries such as chemical processing, oil and gas, and wastewater treatment, this valve is valued for its robust construction, reliability, and efficiency in handling aggressive fluids.
