The Lined Diaphragm Valve is a robust and corrosion-resistant flow control solution ideal for aggressive, abrasive, and high-purity applications. Commonly used in industries such as chemical processing, pharmaceuticals, water treatment, and food & beverage, this valve features a durable lining—typically PTFE, PFA, or rubber—that protects the valve body from corrosive or hazardous media. Its flexible diaphragm isolates the process fluid from the valve’s internal components, ensuring a tight, leak-proof seal and reducing the risk of contamination or wear. 

The smooth, non-stick lining enhances cleanability and supports clean-in-place (CIP) and sterilize-in-place (SIP) systems. Known for its reliability, low maintenance, and excellent sealing performance, the lined diaphragm valve is suitable for both on/off and throttling operations. Whether used in manual or automated systems, it delivers consistent, safe, and efficient flow control. For processes requiring chemical resistance and hygienic assurance, the lined diaphragm valve is a trusted and long-lasting solution.
