A multiport valve for controlling a fluid flow in a fluid circuit, such as a cooling fluid circuit of a motor vehicle, may include a valve housing having at least three fluid connections and a rotary slide for setting the fluid flow. The rotary slide includes at least two fluid channels and is configured to connect two respective fluid connections fluidly via one fluid channel dependent upon its rotary position in relation to its rotational axis. The at least three fluid connections and the at least two fluid channels overlap in relation to a crosswise direction oriented crosswise relative to the rotational axis.
