Zusammenfassung:	A device for blending softened water with hard raw water has one inlet for the raw water, two connections for the inlet to and the outlet from the water softening plant, and one outlet for the blended water. A spring loaded disc valve between the two stop valves for the water softening circuit is designed as a disc valve which opens in the direction of flow. The valve disc surface towards its valve seal is directly exposed to the raw water pressure, and the opposite disc surface to the blended water pressure. This keeps the hardness of the blended water constant, independent of fluctuations of the water pressure or of the water draw-off rate. The new valve is simple and can be produced at low cost.
