Damper valves type AFT-DVH (catalog) serve for the shut-off and/or flow regulation of media such as air and process gas.
Such valves find application in flue gas extraction installations, flue gas desulphurisation, gas utilisation SO2, SO3, NOx, dedusting of furnaces, glass factories, metallurgical plants for copper, zinc, plumb as well as cement factories, etc.
The valves are monolithic of welded construction; bodies can be forged or welded out of steel sheets. Discs can be jointed to the shafts permanently by welding or by dismountable pins (exchangeable discs). For better tightness discs and sealing bars in the body are machined.
