DAMPERS

High Temperature Butterly Damper

The DMA model FCA butterfly damper is a welding assembly construction that consists of a body and a single disc with a centered shaft. The damper must always be installed in horizontal position.
Suitable for low pressures, up to 0.5 bar, and a temperature range of 700ºC up to 1100ºC. The damper is provided with a shaft extension to distance the actuator form the source of heat as well as some heat dispersers in case of high process temperatures. Optionally the valve may also be provided with refractory cement internal lining and special isolating elements as per the requirements marked by the process.
