Coolant valve for a vehicle

A coolant valve for a vehicle, comprising a housing having a plurality of coolant ports, and a spherical-shell-shaped or hemispherical-shell-shaped valve element mounted in a rotatable manner in the housing in order to connect or disconnect coolant ports, and at least one seal arrangement arranged in the region of at least one coolant port, said seal arrangement bearing in a sealing manner against the housing on one side and in a sealing manner against the valve element on the other side, wherein the seal arrangement has an annular carrier element made of a first material and an annular sealing element made of a second material, the second material being softer than the first material, wherein the annular sealing element is connected to and carried by the annular carrier element, wherein the annular sealing element has a first annular sealing lip bearing against the valve element and the annular carrier element has an annular supporting portion adjacent the first annular sealing lip, the first annular sealing lip protruding radially inward beyond a radially inner edge of the annular supporting portion such that a radially inward free end portion of the first sealing lip is exposed beyond the radially inner edge of the annular supporting portion, wherein the radially inward free end portion flexes away from the annular supporting portion as the radially inward free end portion bears against the valve element, and part of the first annular sealing lip being pressed against the annular supporting portion when coolant flows through the coolant valve, wherein the part is located radially outward of the radially inner free end portion, wherein the annular carrier element has a latching portion by which the annular carrier element is latched to the housing, wherein the latching portion has at least one latching protrusion and/or at least one latching receptacle, and wherein the housing has at least one corresponding latching receptacle and/or at least one corresponding latching protrusion.
