PFA Lined Butterfly Valves: The Corrosion-Proof Shield
The FlowBiz PFA Lined Butterfly Valve is specifically designed for industries handling acids, alkalis, and solvents. The core innovation lies in the molding process, where the entire wetted surface—including the body bore and the disc—is encapsulated in a thick, uniform layer of PFA (Perfluoroalkoxy) or Teflon (PTFE).
The FlowBiz Engineering Advantage
- Zero Media Contact: Our valves are engineered so the body is completely inaccessible to the media. The lining extends into the flanged contact faces, acting as an integrated gasket.
- Teflon Muffler/Lining: The high-integrity Teflon lining reduces friction and provides a non-stick surface, preventing material buildup and ensuring smooth operation.
- Bubble-Tight Shut-off: The resilient lining provides a superior sealing surface, achieving bi-directional, leak-proof isolation even in low-pressure vacuum services.
- Thermal Stability: Designed to withstand a wide temperature range while maintaining chemical inertness, making it ideal for the most volatile process lines.

Strategic Industrial Applications
1. Chemical & Pharmaceutical
Perfect for handling hydrochloric acid, sulfuric acid, and high-purity chemicals where contamination must be zero and valve life must be maximized.
2. Fertilizer & Pesticide Plants
Designed to survive the highly corrosive slurry and gas environments typical of agro-chemical manufacturing.
3. Food & Beverage Processing
The inert nature of PFA/Teflon ensures that the valve does not react with food products, maintaining the highest hygiene standards.
4. Water Desalination
Resistant to high-salinity seawater and the aggressive chemicals used in the desalination and reverse osmosis (RO) process.
