A Fluorine-Lined Pneumatic Control Valve is a valve where the inner surface in contact with the medium is lined with fluorine-containing materials (like PTFE).
It uses pneumatic power for control, regulating fluid flow precisely(with positioner), and is ideal for corrosive media due to fluorine's chemical resistance.
