Abstract
Embodiments of a multi-port multi-plane valve are provided. The multi-port multi-plane valve includes a housing which defines an internal cavity. The housing further includes a plurality of ports in which each port lies within one of two planes that are normal to each other. Each of the plurality of ports is in communication with the internal cavity. A shell body is rotatably disposed within the internal cavity and provides selectable fluid communications between the ports. A seal member is also provided which has a plurality of openings and surrounds the shell body. At least one flow enhancer channel may be included to reduce the pressure drop occurring on one side of the valve when controlling flow paths on the other side of the valve.
