The invention relates to a device for the controlled guidance of a polymer melt. Said device comprises a housing (1) having an inlet channel (5) and an outlet channel (6) for the polymer melt in which housing a control element can be displaced between the exits of the inlet channel (5) and the outlet channel (6) perpendicular to the inlet channel (5) and the outlet channel (6) in a sealing manner. A rotatable pin (2, 15) is used as the control element and has a flow channel (3, 16) for the polymer melt to flow through and can be rotated from a first to a second position by means of a rotary arm (9). The aim of the invention is to provide a device of the above type which is compact, inexpensive and allows various functions to be carried out with few different components. For this purpose, the flow channel (3, 16) is eccentric in relation to the rotatable pin (2, 15).
