Heavy Duty Damper Valves

DV

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.
