PFA PTFE FEP Lined Ball Valve With Worm Gear

FVF PFA PTFE FEP Lined Ball Valve With Worm Gear

  • FVF lined ball valve has very high chemical stability, and is applicable for any other strong corrosion media except for molten alkalie and fluorine;
  • FVF lined ball valve with full-bore and floating-ball structure can close the valve within the whole pressure range ensuring zero leakage, which facilitates the pipeline pigging and pipeline maintenance in the system;
  • The integration of closure ball body and valve stem eliminates the possibility that the stem rushes out from pressure-containing parts due to pressure change, which ensures fundamentally the operational safety of the engineering;
  • Reasonable and compact structure and minimum cavity of valve body reduce the sediment of the medium, in addition, special molding process, contributing to excellent airtight sealing surface, enables the valve to be zero leaked by combining with herringbone and annular PTFE packing;
