Specifikace Mezipřírubová klapka 567-568 PVDF-PTFE

Fields of Application:

  • chemical process industry
  • electroplating


  • 50% lower actuation torque compared to a centric butterfly due to the double eccentric operating principle
  • Corrosion resistance and reliability
    Due to the use of high-performance plastics, the new 567/568 PTFE butterfly valves exhibit excellent resistance to corrosion, especially when aggressive media are conducted.
    To guarantee maximum safety, we subject every butterfly valve to a 100% leak and function test before they leave our plant.
  • Low permeability
    With this innovative development the new PTFE butterfly valves, are able to guarantee very low permeability (the degree of penetration). The PTFE passage seal in combination with the FPM backing seal and the media-conveying parts made of PVDF ensure maximum safety when working with media that can diffuse through diverse materials.
  • Chemical resistance and temperature resistance
    The new butterfly valve’s exceptional resistance to acids, salt solutions and hydrocarbons is realized through the integration of the PTFE profile seal in the passage. Additionally, the combination of PVDF/PTFE materials enables a temperature resistance from -20 ºC to +120 ºC.
  • Longer life
    The butterfly valves type 567/568 are designed according to the double eccentric principle, in which the disc does not come into contact with the seal when in the open position, thus exhibiting less wear and tear. For our customers this means a longer service life for their butterfly valves and less maintenance as well.


  • manual valves with hand lever or reduction gear
