PD31W – PN16

PTFE/PFA Lined Diaphragm Valve – engineered for corrosive fluid control with reliable sealing and zero-contamination performance. Designed for chemical, pharmaceutical, and ultra-pure water applications.

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
