Mixing valve

A heating or cooling installation control valve comprising:

• a housing defining a valve space and at least two connection channels which each run out with a first end into the valve space and which each have an opposite second end for connection to a fluid-leading component, one of the at least two connection channels being arranged on one side of the valve space, another one of the at least two connection channels being arranged on another side of the valve space;
• a movable valve element arranged in a valve space;
• and
• a sealing element arranged in at least one of the connection channels at the first end of said at least one of the connection channels, said sealing element being in contact with the valve element, wherein said at least one of the connection channels, in which the sealing element is arranged, in addition to the second end comprises an assembly opening, through which the sealing element is inserted into said at least one of the connection channels and removed from said at least one of the connection channels, wherein the valve space, in addition to the connection channels, comprises a valve assembly opening, through which the valve element is inserted into the valve space and removed from the valve space, the valve assembly opening being arranged at yet another side of the valve space located away from the one side and the another side of the valve space.

A heating or cooling installation control valve comprising:

• a control valve housing comprising an assembly opening, a valve assembly opening, at least two connection channels and a valve space, each channel having a first open end adjacent to the valve space and a second open end for connection to a fluid-leading component, one of the at least two connection channels being arranged on a first side of the valve space, the one of the at least two connection channels facing in a first direction, another one of the at least two connection channels being arranged on a second side of the valve space, the another one of the at least two connection channels facing in a second direction, the valve assembly opening being in fluid communication with the valve assembly space, at least one of the at least two connection channels being associated with the assembly opening and in fluid communication with the assembly opening, the valve assembly opening facing in a direction different from a direction of the assembly opening;
• a movable valve element inserted into the valve space via the valve assembly opening, the valve assembly opening being arranged on a third side of the valve space, the third side being located at a spaced location from the first side and the second side, the valve assembly opening facing in a third direction, the third direction being different from the first direction and the second direction;
• and
• a sealing element removably inserted into the assembly opening such that the sealing element is arranged in at least one of the connection channels at the first end of the at least one of the connection channels, wherein the sealing element seals the first end of the at least one of the connection channels, the sealing element being in contact with the valve element.
