A valve arrangement (602, 604) comprising a number of valves (602a-602d, 604a-604d) is provided. The valve arrangement (602, 604) is configured to be in a first mode and a second mode. In the first mode sections (606, 608, 610, 612, 614, 616, 618, 620, 622, 624) in a heat treatment apparatus (600) are passed by a product in a first order, and in the second mode the sections are passed in a second order. Since the first order is different from the second order, the first order can be used for full capacity production and the second order can be used for half capacity production. |
