PFA/FEP Diaphragm Valves
PFA/FEP Lined Diaphragm Valves are corrosion-resistant flow control valves designed for safe and leak-proof handling of aggressive and toxic chemicals in process industries.
Product Overview
PFA/FEP Lined Diaphragm Valves are ideal for highly corrosive and ultra-pure fluid applications. The valve body is lined with PFA or FEP fluoropolymer, offering superior chemical resistance and non-contaminating performance. The flexible diaphragm isolates the process media from the valve internals, ensuring zero leakage and preventing metal contact with corrosive fluids.
These valves are particularly suitable for on/off and throttling services in chemical, pharmaceutical, and water treatment industries. Their simple design, ease of maintenance, and smooth flow control make them a trusted choice for handling acids, alkalis, solvents, and other aggressive media.
