We design and produce butterfly dampers for the petrochemical, cement, glassware, paper and air-smoke ducts of conventional boilers. The butterfly dampers have mainly wing-type blades, with a seal rating of up to 99.9% and are suitable for adjustment and sealing. Only in the case of biplane blades are they pressurized.
We also produce dampers with a circular section, suitable for regulation and interception in refineries and in the extraction of oven fumes. With wing blades and opposing blade movement, they have a seal up to 99.9% and are often internally lined with refractory material.
