1. A multi-way valve for use in medicine or medical technology with at least one basic housing through which a medium can flow at least in sections and in which an actuator is held in a rotating manner about a central axis, wherebythe basic housing has at least two connection points for the inflow and outflow of the medium and forms an actuator receptacle which has a peg arranged concentrically in relation to the central axis and on the inside of the basic housing a radially encircling cut-out, andthe actuator has an operating element and an essentially hollow cylindrical section which holds the peg of the actuator receptacle at least in sections, has at least one throughflow opening for the fluidic connection of at least two connection points and, on the outer side of the cylindrical section, at least one radially encircling moulding andthe peg of the actuator receptacle has at least one counterbearing for the actuator to form a sealing surface in the area of at least one connection point,whereinthe peg has at least one flattened area on the circumference in relation to the central axis and the moulding of the actuator engages in the cut-out of the actuator receptacle in order to fix the actuator in the actuator receptacle in a positive-locking and fluid-tight manner and the throughflow openings of the actuator are designed as gates which are open at the end of the hollow symmetrical section of the actuator.
