Design Features

Design Characteristics

  • free of cavities
  • maintenance free – self lubricating
  • mounting-flange for actuators acc. to DIN ISO 5211
  • easy accessible adjustment of the plug, even with mounted actuator
  • with chemical resistant lining – thickness min. 3 mm
  • fugitive emmission resp. clean air act certified (TA – Luft 2002 approval)
  • Directive 2014/68/EU
  • FDA conformity

The specified values depend on the respective application (medium). Operating temperatures under -20°C only with body material 1.4408 or low-temperature steel. Hight pressure resistance / temperature resistance on request, e.g. PN 40.

Sleeve: There are different sleeve materials / compounds available.
