Abstract: A heating or cooling installation control valve includes a movable valve element which is arranged in a valve space (8), as well as at least two connection channels (24, 26) which each have a first end in fluidic connection with the valve space (8) and have an opposite second end (A, B) for connection to a fluid-leading component. A sealing element (18) is arranged in at least one of the connection channels (24, 26) at a first end thereof. The sealing element is in contact with the valve element (6). The at least one connection channel (24, 26), in which the sealing element (18) is arranged, in addition to the second end (A, B), includes an assembly opening, through which the sealing element (18) can be inserted into the connection channel (24) and removed from of the connection channel (24).
