Abstract:
Valve device for flow control in a distributor of a liquid-operated heat and cold energy supply system having a flow measuring unit to measure a flow rate of the liquid and having a control element to adjust a flow area for the liquid, the maximum flow area being variable through the rotation of the control element, characterized in that the control element is designed as a first disc with at least one flow limiting aperture, and is part of a control unit, the control unit comprising a second disc, which exhibits at least one flow aperture, is arranged in parallel to the first disc and adjoins said first disc, forming a tight connection, the at least one flow limiting aperture and the at least one flow aperture being positioned such that a total area made up of the areas of the at least one flow aperture and the at least one flow limiting aperture, which overlap each other, is variable as a function of a rotation of the first disc relative to the second disc around a rotational axis.
