| description | A valve (10) for the temperature-dependent control of at least one hydraulic load includes a valve housing (12) with a tank connection (T), a working connection (A), and a supply connection (P). A control piston (30) controls the connections (A, P, T), is moveable in the valve housing (12) and is preloaded by a working spring (74). A thermal element (62) can be supplied with a fluid at a specifiable temperature (TFIuid) and is actively coupled to the control piston (30). The control piston can be moved by control pressure present at the supply connection (P). The thermal element (62) interacts with the working spring (74) such that the thermal element causes a temperature-dependent change of the preload force acting on the control piston (30). |
