The system has a mounting frame (2) and a valve frame (1) connected with each other in a contact region by a fastening unit (14) e.g. screw. Recesses (12, 13) are provided in the contact region. A centering element (15) i.e. plastic disk, has an outer contour adapted to the recesses and an inner contour adapted with a cross section of the fastening unit. The element is made of a material e.g. polyamide, which permits displacement of the fastening unit of about 1/200 of length and breadth of the mounting frame in a displacement direction blocked through the element with increased temperature. |
