PTFE Lined Diaphragm Valve

MVS Valves PTFE Lined Diaphragm Valve is a high-performance solution for industries that demand corrosion resistance, bubble-tight shut-off, and contamination-free operation. Engineered with a Weir A Type cavity-free design, this valve ensures smooth and sterile media flow, making it a preferred choice in chemical, pharmaceutical, and biotech processes. The body lining is available in Polypropylene (PP), PTFE, FEP, PFA, and PVDF, all of which provide outstanding resistance to aggressive chemicals and ensure longer service life. With size ranges from DN 15 to DN 250 and pressure ratings up to PN 16 (ANSI Class 150), these valves are available in ductile iron, carbon steel, and stainless steel construction, with options for manual, pneumatic, and electric actuation.

The strong PTFE backed by EPDM or Neoprene rubber diaphragm makes sure tight sealing while resisting both temperature and chemical wear. These lined diaphragm valves are manufactured as per international quality standards and tested rigorously to ensure compliance with operational and safety benchmarks. The PTFE Lined Metal Diaphragm Valves are engineered to handle extreme media in continuous and batch processing systems, ensuring consistent performance over extended cycles.

For applications requiring clean, reliable shut-off, Fluoropolymer Lined Diaphragm Valves, including PFA Lined Diaphragm Valves, FEP Lined Diaphragm Valves, and PVDF Lined Diaphragm Valves, deliver excellent thermal and chemical resistance. MVS also offers Fluorine Lined Diaphragm Valves and Fluoroplastic Lined Diaphragm Valves, which are particularly effective in high-purity processes. Whether you require Weir A Type Plastic Lined Diaphragm Valves or Fully Lined Weir A Type Diaphragm Valves, each product is built for reliability, ease of maintenance, and precise control.

Our wide range of valves also includes PTFE Lined Weir Type Diaphragm Valves, PFA Lined Weir Type Diaphragm Valves, and PVDF Lined Weir Type Diaphragm Valves, which are suitable for aggressive chemical services, chlor-alkali plants, and acid dosing systems. For larger industrial setups, we manufacture DN 200 (8″) and DN 250 (10″) Big Size Weir Type PTFE Lined Diaphragm Valves, offering robust operation under high-flow conditions.

MVS makes sure consistent quality across all configurations, including PTFE Diaphragm Valve, Fluorocarbon Resin Lining Diaphragm Valves, and Corrosion Acid Chemical Resistance Lining Diaphragm Valves, delivering long-lasting performance even in extreme conditions.
