Frequently Ask Questions

What Is an FEP/PFA Lug Type Butterfly Valve?

It is a lug-type butterfly valve internally lined with FEP or PFA fluoropolymer material, designed to provide corrosion-resistant flow isolation for aggressive chemical and industrial media.

What Is the Difference Between FEP and PFA Lining?

Both are fluoropolymer materials with excellent chemical resistance. PFA generally offers better high-temperature capability and melt-processing characteristics, while FEP is also highly chemically resistant and suitable for many corrosive applications.

Why Is FEP/PFA Lining Used?

FEP and PFA provide excellent resistance against many aggressive acids, alkalis, solvents and corrosive chemicals, helping protect the valve body from direct contact with the process media.

Who Is an FEP/PFA Lug Type Butterfly Valve Manufacturer in India?

Alis Valves manufactures and supplies FEP/PFA Lug Type Butterfly Valves for chemical processing, pharmaceutical, fertilizer, water treatment and highly corrosive industrial applications.
