Abstract: A valve device for controlling a fluid flow includes a flow control valve (15) having a valve housing (19) with a supply connection (9) and a user connection (11). A valve piston (17) is guided inside the valve housing (19) longitudinally moveable and controls the passage to the user connection (11) by a thermocouple (61) via an orifice (37, 39) depending on the temperature of the fluid flow. A pressure compensator (21) is connected to the supply connection (9) and keeps the pressure drop across the orifice (37, 39) constant.

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.
