FlowBiz PFA/FEP Lined Butterfly Valves: The Ultimate Shield Against Corrosion
In the high-stakes chemical and pharmaceutical sectors of Pune, managing aggressive media like concentrated acids, alkalis, and reactive solvents requires more than just standard stainless steel. FlowBiz Exports Pvt. Ltd. is the premier PFA Lined Butterfly Valve Manufacturer in Pune, providing "Stalwart" solutions where even high-grade alloys fail.
Our lined butterfly valves combine the mechanical strength of a metallic body with the near-total chemical inertness of fluoropolymer linings (PFA/FEP), ensuring a leak-proof and contamination-free process.
The Fluoropolymer Advantage: PFA vs. FEP Lining
FlowBiz offers two primary lining options to match your specific temperature and chemical concentration profiles:
- PFA (Perfluoroalkoxy): Ideal for high-temperature applications (up to 200°C). It offers superior melt-strength and resistance to permeation, making it perfect for ultra-pure chemicals and aggressive acids.
- FEP (Fluorinated Ethylene Propylene): A cost-effective alternative for moderate temperatures (up to 150°C). It provides excellent chemical resistance and a low coefficient of friction for smooth operation.
Key Features of FlowBiz Lined Butterfly Valves
- Total Encapsulation: The valve disc and the entire internal body bore are fully encapsulated with a minimum lining thickness of 3mm to 5mm, ensuring zero metallic contact with the process fluid.
- Bubble-Tight Sealing: The energized seat design ensures a 100% leak-proof shut-off, meeting API 598 zero-leakage standards.
- Blow-out Proof Stem: Engineered for safety, our stems are designed to prevent ejection under high-pressure transients.
- Low Operating Torque: The naturally "slippery" nature of PFA/FEP reduces friction between the disc and the seat, allowing for smaller, more economical actuators.
- Contamination-Free: The non-stick surface prevents product buildup, making it ideal for the pharmaceutical and food-processing industries in Pune.
