Frequently Ask Questions
A PTFE Lined Control Valve is a control valve whose process-contact surfaces are protected with PTFE (Polytetrafluoroethylene) to provide corrosion resistance while regulating the flow of aggressive process fluids.
The major advantage is corrosion resistance combined with automatic flow control. It allows a control valve to be used in applications where an unlined metal valve may not provide adequate chemical resistance.
Yes. Depending on the design, the plug and seat can be provided with PTFE or other fluoropolymer materials.
PTFE is used because it has excellent resistance to a wide range of acids, alkalis and other corrosive chemicals. It protects the underlying valve body from direct contact with the process media.
Alis Valves manufactures and supplies industrial PTFE-lined valves for corrosive and chemically aggressive process applications, including PTFE/PFA/FEP/ETFE/PVDF-lined valve solutions.
