1. A fluid valve, comprising:
a valve body having multiple internal flowpaths and configured to be rotatable about a rotation axis; and
a housing in which the valve body is at least partially disposed, and comprises:
a first port disposed on a first side of a normal plane in relation to the rotation axis;
a third port disposed on a second side of the normal plane in relation to the rotation axis, which is opposite the first side of the normal plane; and
a second port radially spaced apart from the rotation axis and in a direction of the rotation axis is disposed between the first port and the third port on the normal plane;
a fourth port which is radially spaced apart from the rotation axis and in a circumferential direction about the rotation axis is disposed on the normal plane:
spaced apart from the first, the second and/or the third port and/or
in the direction of the rotation axis between the first port and the third port;
wherein the valve body in at least one rotary position connects at least two ports of the housing to one another via the multiple internal flowpaths, and in at least one other rotary position does not connect the at least two ports to one another,
wherein the multiple internal flowpaths comprise two separate flow paths through the valve body based on the rotary position of the valve body, and
wherein the valve body is configured such that each port on the normal plane is connectable to each circumferentially adjacent port on the normal plane through the valve body, and
wherein the first port is always connectable to at least one of the circumferentially adjacent ports on the normal plane via the internal flowpath, and
wherein the third port is connectable to at least one of the circumferentially adjacent ports on the normal plane via the internal flowpath and the first port and disconnectable from the first port.
