The DMAR model FCA butterfly damper is a welding assembly construction that consists of a body and a single disc with a centered shaft and rectangular or square section.
It is metal-metal seat and it can get a tightness by area (efficiency) between 96% and 98%. Furthermore, the shaft is extended in order to protect the actuator from the media’s temperature.
If the process requires it, refractory concrete coatings and special insulators will be applied to reduce the skin temperature.
