The invention relates to a control device for actuating a control valve, which controls a fluid coolant volumetric flow and which can be designed as a slide valve, flap valve, ball valve, rotary slide valve, roller valve, disk valve, or the like. The problem addressed by the invention is that of developing a device for actuating a control valve, which control valve controls a fluid coolant volumetric flow. The control valve can be used in connection with ambient temperatures of over 120°C to 950°C and is characterized by an economical, robust structural design that is simple in terms of production and assembly. The control device according to the invention for actuating a control valve (1), comprising a flow housing (2) having connection pieces (3) arranged on the flow housing (2), which connection pieces are used either for the inflow (4) or the outflow (5), and comprising an actuating element (6), which is arranged on the control valve (1) and which protrudes from the flow housing (2) and is sealed to the flow housing (2) in a liquid-tight manner, such that an electrical actuator (7), which is arranged in the liquid-free space outside of the flow housing (2) and is positionally fastened to the flow housing, can act on the actuating element (6) arranged on the control valve (1), is characterized in that an actuator housing (8) cooled by the same fluid coolant volumetric flow is arranged on the flow housing (2), in which actuator housing the actuator (7) is arranged in a dry and positioned manner, the coolant inlet(s) (10) being connected directly to the flow housing interior (17), which is adjacent to the control valve (1) on the inflow side, and the coolant outlet(s) (11) being connected separately to the coolant circuit. |
