PTFE PFA FEP Lined Downward Spreading Discharge Valve

FVF PTFE PFA FEP Lined Downward Spreading Discharge Valve

  • FVF lined discharge valve features light switch, small volume, reliable sealing, simple structure and easy maintenance.
  • It is mainly used at the bottom of the storage tank, reaction kettle and other containers. It eliminate the process medium residual phenomenon, according to the actual situation.
  • The valve body, disc(ball) and other wetted parts in contact with the medium is lined by fluorine plastic FEP, PTFE and PFA. It can sustain any corrosive medium except for the molten alkali metals and flurine elements.It is the ideal product to use in chlor-alkali, industrial in organic chemicals, metal and mining, nitrogen and phosphatic, fertilizers, petroleum refining, pharmaceutical etc.
