  • Application 1
    For standard use without media flow
  • Application 2
    For complicated media requirements, such as acids and dry servicet

Product advantages
  • Ideal for use in vacuum
    due to the vulcanized seat ring on a metal ring
  • Excellent control behaviour without hysteresis
    with firm, play-free disc/stem connection and centric valve disc
  • Valve design cavity-free
    makes simple sterile cleaning possible and choice of body material independent from the medium
  • Long service life
    seals tightly at full differential pressure even with very high switching cycles.
  • Excellent bubble-tightness
    Multi-functional seat-ring easily exchangeable, maintenance-free, long service life, reliable sealing in the seat, to the flanges and at the stem bore; safe locking in dovetail, embedded in the body without edge projection to the flange surface
  • Absolutely maintenance-free seal system
    the bearing with O-ring prevents foreign substances from penetrating from the outside
  • Universal range of application
    for almost all media, from use with acids to the sensitive food and pharmaceutical industrys
  • Economic and easy assembly of all actuator types
    the standard top flange according to DIN/ISO 5211 makes it possible to mount all common actuator types

Application range
Industries and applikations
  • Water / Sewage
  • Engineering
  • Food industry
  • Chemical and petrochemical industry
  • Colouring, Varnish, Dyeing factories
