Engineered for Harsh Chemistry: The DN40 PFA-Lined Diaphragm Valve

Aggressive media can compromise system integrity, the DN40 diaphragm valve with PFA lining delivers unmatched corrosion resistance. Engineered for chemical processing, pharmaceuticals, and wastewater treatment, this valve ensures operational safety and durability in highly corrosive environments. Its PFA lining forms a robust barrier against acids, bases, and solvents, reducing maintenance frequency and system downtime. With decades of manufacturing expertise, our company has helped facilities worldwide optimize flow control with high-performance valves built for the most demanding applications.
 
 Technical Performance & Compliance at a Glance
The DN40 valve complies with EN558-1 Series 1 dimensional standards, ensuring compatibility with European systems. Its PFA (perfluoroalkoxy) lining offers superior chemical resistance compared to PTFE or rubber alternatives. Operating pressures range up to PN10, and the valve maintains integrity from -20°C to +180°C, depending on the process fluid. The body material is typically ductile iron or stainless steel. Our valves meet or exceed DIN, ISO, and ASTM quality benchmarks and are FDA, RoHS, and ATEX compliant for global deployment in regulated environments.
