The PTFE Seat & PFA Coated CF8 Disc Butterfly Valve represents a premium solution for handling the most aggressive chemical media and ultra-pure processes. This valve combines a PTFE seat with a PFA-coated CF8 (SS304) stainless steel disc, creating an unparalleled barrier against corrosion, contamination, and chemical attack in critical industrial applications.

Key Advantages:

1. Dual Protection Design

  - PTFE seat ensures excellent chemical resistance and bubble-tight sealing

  - PFA coating on CF8 disc provides superior protection against pitting and crevice corrosion

  - Ideal for handling strong acids, alkalis, and solvents

2. Enhanced CF8 Stainless Steel Core  

  - CF8 (SS304) disc substrate offers excellent mechanical strength

  - PFA coating extends service life in harsh chemical environments

  - Maintains structural integrity at elevated temperatures

3. Zero Contamination Guarantee  

  - Non-stick, non-absorbent surfaces prevent product contamination

  - Smooth finish minimizes particle adhesion and bacterial growth

  - Perfect for pharmaceutical and food grade applications

4. Superior Temperature Resistance  

  - PTFE seat withstands temperatures from -20°C to 200°C

  - PFA coating maintains stability in high-temperature processes

  - Suitable for steam and hot media applications

5. Optimal Flow Characteristics  

  - Precision-engineered disc design minimizes pressure drop

  - Full bore available for applications requiring minimal flow restriction

  - Smooth operation with low torque requirements

Typical Applications:

- Pharmaceutical and Biotechnology Processes

- Chemical Manufacturing and Processing

- Food and Beverage Production

- Semiconductor and Electronics Manufacturing
