The invention describes and illustrates a throttle valve arrangement (1) for an exhaust gas tract or a feed air tract of an internal combustion engine, comprising a throttle valve housing (2) for receiving a pivotably mounted throttle flap, wherein the throttle valve housing (2) has at least one outer housing (3a) and at least one inner housing (3b), the outer housing (3a) being designed to at least partially accommodate the inner housing (3b). The aim of the invention is to provide a throttle valve arrangement which, on the one hand, has a high temperature and corrosion resistance and, on the other hand, is designed in a simple and cost-effective manner. This aim is achieved in that an air gap (4) is present at least in some regions between the outer housing (3a) and the inner housing (3b). In addition, the invention relates to a method (19) for producing such a throttle valve arrangement (1).
