Pneumatic lined-PTFE control valve is an anti-corrosion straight-through single-seat control valve. The inner wall of the valve body and the valve components in contact with the fluid are made of high-pressure injection molding technology and are lined with polyperfluoroethylene-propylene (F46) that is resistant to corrosion and aging. Sealed with polytetrafluoroethylene bellows. It is widely used in the control of strong corrosive media such as acids and alkalis, as well as toxic and volatile gases and liquids.
