GENERAL INFORMATION

Butterfly Valve DKZ 103

Series 103 is a tight-seal interposed flange Valve for flanges as per DIN EN 1092. The Valves are absolutely air-tight in line with DIN EN 12266 Leak Rate A. The housing is one-piece, the sealing sleeve is loose, glued or vulcanised. The ShutOff Valve is suitable for solid, liquid and gaseous media and the temperature range is from – 40 to + 200°C. This series is also available as a throttle Valve (metal seal closure) for hot gases with a temperature over 200°C.

  • maintenance-free design
  • argely self-supporting housing
  • centrally-positioned valve disk designed to promote a good flow,
    with special shaft connection, giving an absolute seal in both directions of flow
  • seals with lateral overlap and an additional sealing rim give a
    perfect seal between the flanges without any extra flange seals
  • Also available in Ex version for the application in zone 0/20 incl. EC-type examination
  • The shaft end and the armature head are designed to fit to a wide range of drives.
    Interfaces as per DIN EN ISO 5211
