The PTFE Lined Wafer Type Butterfly Valve delivers uncompromising chemical resistance and purity for the most aggressive and contamination-sensitive processes. This valve features a body fully lined with PTFE (Polytetrafluoroethylene), creating an inert flow path that is completely isolated from metal components, making it the definitive choice for handling strong acids, alkalis, solvents, and ultra-pure media in a space-saving wafer format.

Key Advantages:

1. Complete PTFE Lining

• The entire internal wetted surface—body and disc—is protected by a seamless PTFE lining, offering exceptional resistance to virtually all corrosive chemicals.

• Ensures no media contact with the metallic valve body, preventing corrosion and metallic contamination.

2. Superior Purity & Non-Stick Surface  

• The ultra-smooth, inert PTFE surface prevents scaling, particle adhesion, and bacterial growth.

• Ideal for pharmaceutical, food & beverage, and high-purity water applications where product integrity is critical.

3. Compact & Cost-Effective Wafer Design

• Installs easily between ANSI/DIN/JIS standard flanges, reducing weight, space, and overall installed cost compared to flanged lined valves.

• Maintains a leak-tight seal via flange compression without the need for special gaskets.

4. Bubble-Tight Sealing & Reliability

• PTFE-to-PTFE seating surface ensures excellent, long-lasting shut-off with minimal torque.

• Suitable for a wide temperature range and vacuum service applications.

5. Low Maintenance & Long Service Life

• The inert lining resists chemical attack and wear, drastically reducing maintenance needs and downtime in harsh processing environments.

Typical Applications:

• Chemical & Pharmaceutical Processing

• Acid and Alkali Dosing Systems

• Ultra-Pure Water (UPW) & WFI Systems

• Semiconductor Manufacturing

• Agrochemical and Dye Production
