Fluorine lined gate valve is a kind of opening and closing valve with see, using both sides of the face sealing wedge-shaped gate to connect or cut off the pipeline medium, wedge gate valve is not allowed to micro-open in the pipeline for throttling device, so as not to accelerate the damage of the sealing surface due to the high-speed flow of the media erosion.FEP (F46), PCTFE (F3) fluorine lined valves for use in the concentration of hydrofluoric acid at -50 ℃ ~ 150 ℃, and acid, strong acid, strong oxidizing agent, FEP is also suitable for the concentration of strong alkali solvents and other corrosive gases, liquid media pipeline use. Oxidizer, FEP is also suitable for the concentration of strong alkali solvents and other corrosive gases, liquids and media pipeline use.
