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