The valve piston 12 and the valve head 13 are designed as one piece and consist of tungsten carbide. Furthermore, the control valve comprises different constructions across the entire control valve range. For example, the valve housing 100, the valve seat 6 and a packing retainer 14 are optionally shaped such that the inner hollow space tapers continuously from the valve inlet to the valve seat 6, which prevents evaporation upstream of the valve seat 6. Furthermore, the double control valve consists of a large sub-valve 36 and at least one small sub-valve 37, wherein the large sub-valve 36 is designed as an adjustable open-closed piston valve and the small sub-valve 37 is designed as a control valve.
