Heavy Duty Damper Valves With Refractory Lining

DV-HT

Designed for heavy duty applications and installed in major plants over Europe, its main function is for the shut-off and/or regulation of media such as air or process gas.


Its welded construction gives full freedom of customization and allows building the valves in the most accurate way to withstand the harshest process conditions.


For special high temperature applications, ceramic lining inside the body is available according to customer requirements.


Common uses
  • Dedusting of furnaces

  • Glass factories

  • Metallurgical plants for copper, zinc, lead

  • Heat recovery

  • Pyrolizis and gazification units

  • Regenerative oxidation device (RTO)

  • Organic Rankine Cycle units (ORC)

  • Cement factories

  • ...

Product properties:

range of diameters: Ø 50 mm – Ø 5 000 mm (and other sizes on request)

It is important to always specify the internal dimensions and the lining thickness (Ceramic or concreate). It is also usefull to know the lining applied on the ducts.
