A valve piston () is guided inside the valve housing () longitudinally moveable and controls the passage to the user connection () by a thermocouple () via an orifice () depending on the temperature of the fluid flow. A pressure compensator () is connected to the supply connection () and keeps the pressure drop across the orifice () constant.
