Abstract
A control apparatus for a liquid medium including a body portion provided with flow channels. The body portion includes an inlet for the medium, an outlet for the medium to an apparatus that the medium is conducted to, a return point for the medium returning from the apparatus, and a discharge point through which the medium is discharged from the control apparatus. A flow control valve and flow and pressure measuring devices are arranged after the medium inlet in the flow channels of the body portion. A pressure control valve for controlling the pressure in the flow channels between the flow control valve and the pressure control valve is arranged after the return point. For safety reasons, a pressure relief valve is arranged in the channel system of the body portion provided by the flow channels between the flow control valve and the pressure control valve, the relief valve being arranged to open as the pressure exceeds a certain allowed value.
