Worm gear flange full lined butterfly valve specification
Profile

Fully fluorine lined butterfly valve can adapt to some corrosive environment of strong acid or strong alkali in many special fields such as petroleum, chemical engineering and food. Fluoroplastics such as PTED and F46 can be lined in regular butterfly valve and on its valve plate to separate the medium form the valve body and achieve corrosion resistance. Butterfly valve lined with PTED and that lined with rubber can be used as a king of component to achieve the on-off of pipeline system and flow control, which are widely applied to fields such as petroleum, chemical engineering, metallurgy and water and electricity.

Details
  1. Simple structure, small and light.
  2. Strong corrosive resistance, stable performance, difficult to be aging and low friction coefficient.
  3. Seamless valve body design to ensure the sealing between valve body and valve seat and the even stress of valve body and valve seat.
  4. Adjustable gland design to prolong the service life of valve body.
  5. Two-way valve sealing to ensure no leakage of medium.
  6. One-piece design of valve rod and valve clack and reinforced sealing type to ensure torque.
