Abstract: Valve device. 2. Valve device for controlling a fluid flow, consisting of a flow control valve (15), which comprises a valve housing (19) with at least one supply connection (9) and one user connection (11) as well as a valve piston (17) that is guided inside the valve housing (19) longitudinally moveable and which controls the passage to the user connection (11) by means of a thermocouple (61) via an orifice (37, 39) depending on the temperature of the fluid flow, and a pressure compensator (21), connected to the supply connection (9), keeps the respective pressure drop across the orifice (37, 39) constant.
