【Product Introduction】:

Wafer Triple Offset Butterfly Valve shown in the figure is a worm gear made of carbon steel material. The seat sealing material can be a full metal ring, and can be made of a graphite type laminated metal, which is elastic. The PTFE seat seal is a flexible seat butterfly valve. This seat can be design and produced as zero leakage type and suitable for corrosive medium.It is easy to produce and costs less than all metal seat butterfly valves.


【Application Of PTFE Seal-ring】:

PTFE people aslo call it Teflon.It has high temperature resistance, corrosion resistance, excellent electrical insulation, aging resistance and other characteristics.Resistant to the corrosion of almost all chemicals, but by molten alkali metal erosion. ZFVALVES Butterfly valve often uses PTFE as the valve seal-ring.PTFE has become the main corrosion resistant material in petroleum, chemical and textile industries due to its excellent corrosion resistance.As Seal ring the working temperature is -29℃~150℃.

*  PTFE Mechanical property:

   σb (MPa):20.7~27.5

   δ5 (%):250~350

   αk (J/cm2):>98.1

   HARD(HB):50~65D

* Thermal properties:

   Distortion temperature:1.86MPa:55℃; 0.46MPa:120℃

   Martin temperature:250℃
