Summary
  Pneumatic fluorine lined butterfly valve is also known as pneumatic lined anticorrosive butterfly valve. It is in contact with the official media flow components (such as the valve body wall, valve plate, seat) lined with a thicker layer of fluorine plastic, and it has a strong corrosion resistance and wear resistance. Pneumatic fluorine lined butterfly valve seat and disc plate are all made of PTFE, which effectively ensure that the valve shaft and other related parts from the valve cavity media contact and corrosion. Pneumatic fluorine lined butterfly valve according to the connection mode, it is divided into pneumatic clamp type fluorine lined butterfly valve and pneumatic flange type fluorine lined butterfly valve. At the same time, it also can choose switch mode according to the working condition of requirements or execution of external regulation device, to achieve rapid pipeline medium to switch off or adjust flow using proportion type. It can be widely used in the corrosive fluids with temperature of 180 ° C or as well as strong acid, strong alkali medium under normal circumstance.
