PTFE/PFA Lined Diaphragm Valve is specifically designed to handle highly corrosive and high-purity media. With a full PTFE or PFA lining, the valve ensures maximum chemical resistance while maintaining clean, contamination-free operation.
Its weir-type diaphragm design provides tight shut-off, smooth flow regulation, and bubble-tight sealing, even under demanding process conditions. The valve construction eliminates dead spaces, minimizing the risk of product buildup and ensuring process integrity.
Key Features & Benefits:
-
Full PTFE/PFA Lining – excellent resistance to aggressive chemicals and solvents.
-
Hygienic Flow Path – ideal for ultra-pure and contamination-sensitive applications.
-
Reliable Shut-Off – diaphragm design ensures leak-free performance.
-
Easy Maintenance – minimal moving parts, simple replacement of diaphragms.
-
Versatile Use – suitable for both on/off service and flow regulation.
Typical Applications:
-
Chemical processing plants
-
Acid & solvent distribution systems
-
Pharmaceutical manufacturing
-
Semiconductor & ultra-pure water facilities
-
Food & beverage industries requiring contamination control
