Design Features

Design Characteristics

  • Heating from flange to flange
  • heating of cover area (type HM)
  • solid casted heating jacket
  • solid casted connections for heating medium
  • several heating jacket connections available (e. g. female threads / flanges / weld ends)
  • available with drain connection for condensate (optional)
  • oversize design (optional)
  • available for almost all valve types (e. g. plug valves with weld ends, sample valves, fully lined valves, sight glasses etc.)

Operating temperatures < -30°C and > 220 °C have to be checked and approved by AZ according to the operating conditions.

Besides the P/T value of the sleeve the limitations of the valve bodies also have to be considered. Please refer to the EN 12516-1 resp. ASME B16.34 in order to choose a proper pressure rating (PN/class). The shown values refer to austenitic stainless steel 1.4408 (A351 Gr. CF8M).

1) For operating temperatures below -10°C low temperature / austenitic steels are required.
2) Sleeve: There are different sleeve materials / compounds available.
