| abstract |
The invention relates to a valve arrangement (1), having a valve (2), which controls a flow of a heat-transfer medium through a heat exchanger arrangement, which comprises a primary side and a secondary side (11), and having a valve actuating device, which comprises a thermostat element (6), which is exposed to a temperature on the secondary side (11) and can be acted on by a temperature- and/or pressure-influencing device (14). The aim of the invention is to achieve good control behavior and fast reaction. For this purpose, the temperature- and/or pressure-influencing device (14) is influenced by a physical variable that can be determined at the valve (2) or the heat exchanger arrangement. |
