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
...
