Frequently Ask Questions
A PTFE Lined Diaphragm Valve is a diaphragm valve whose wetted body surfaces are protected with PTFE lining to provide high resistance against corrosive and aggressive process fluids.
The diaphragm also isolates the process fluid from the valve's operating mechanism
A PTFE diaphragm is preferred where the process requires high chemical resistance.
Bare metal may corrode when exposed to aggressive chemicals.
A properly applied PTFE lining provides a chemically resistant barrier between the process fluid and the body material.
Its primary advantage is excellent chemical and corrosion resistance, making it suitable for aggressive acids, alkalis and other corrosive process fluids.
Alis Valves is a PTFE Lined Diaphragm Valve manufacturer and supplier in India, providing corrosion-resistant valve solutions for chemical processing, acid and alkali handling, pharmaceutical, water treatment, fertilizer, wastewater and other industrial applications.
