Fluorine Lined Lifting-Type Check Valve for the control of corrosive or strongly corrosive media, the valve body cavity surface covered with PTFE plastic, with high strength, good corrosion resistance; applicable to different work temperature and fluid pipeline, to prevent all kinds of pipeline or equipment on the media backflow of the one-way opening and closing. Applicable to various concentrations of strong alkali organic solvents and other corrosive gases, liquids and media pipeline use.The Lifting-type check valve’s structure is similar to the general disconnecting valve, its valve flap along the channel center for lifting movement, reliable action, generally can only be installed in the horizontal pipeline, lifting the common characteristics of vertical check valve valve valve flap along the valve access axis to do the lifting movement, generally should be installed in the vertical pipeline.
