Frequently Ask Questions
A Floating PFA/PTFE Lined Ball Valve uses a floating ball with PFA or PTFE lining to provide reliable isolation of highly corrosive and chemically aggressive fluids.
Both materials offer excellent chemical resistance. PFA generally provides better temperature capability and mechanical properties, while PTFE is widely used for reliable corrosion-resistant lining applications.
Alis Valves manufactures and supplies Floating PFA/PTFE Lined Ball Valves for chemical, pharmaceutical, petrochemical, and other corrosive industrial applications.
They are mainly used for handling acids, alkalis, corrosive chemicals, and aggressive process fluids in chemical and process industries.
Yes. PFA/PTFE-lined valves are suitable for many strong acids, alkalis, and aggressive chemicals, subject to chemical compatibility and operating-temperature requirements.
The floating design provides effective downstream sealing with a relatively simple and compact construction, making it suitable for many chemical applications.
