Rotary plate valve systems

A rotary valve system, comprising:

• a first valve body having a first plurality of fluid channels, each one of the first plurality of fluid channels having a common first inlet to receive a fluid and a first outlet, the first plurality of fluid channels diverging downstream of the common first inlet to define a first cavity within the first valve body, the first cavity surrounded by the first plurality of fluid channels, the first plurality of fluid channels comprise four first fluid channels defined within the first valve body that are spaced apart about a perimeter of the first valve body, each one of the four first fluid channels extends from the common first inlet along a common wall and diverges downstream from the common first inlet to define the first cavity;
• a second valve body coupled to the first valve body, the second valve body having a second plurality of fluid channels, each one of the second plurality of fluid channels having a second inlet and a common second outlet, and the second plurality of fluid channels comprise four second fluid channels defined within the second valve body that are spaced apart about a perimeter of the second valve body, with each one of the first fluid channels in selective fluid communication with a respective one of the second fluid channels;
• and
• a plate assembly having a plate coupled between the first valve body and the second valve body, the plate defining a plurality of openings, the plate movable between at least a first, open position in which each first outlet of the first plurality of fluid channels is in fluid communication with a respective second inlet of the second plurality of fluid channels and a second, closed position in which the second inlet of each of the second plurality of fluid channels is completely obstructed by the plate, and a portion of the plate assembly is received within the first cavity.

• a plate assembly having a plate coupled between the first valve body and the second valve body, the plate defining a plurality of openings, the plate movable between at least a first, open surge position in which the first outlet of a first sub-plurality of the first plurality of fluid channels is in fluid communication with the second inlet of a first sub-plurality of the second plurality of fluid channels, a second, closed position in which the second inlet of each of the second plurality of fluid channels is completely obstructed by the plate, and a third, open load position in which the first outlet of a second sub-plurality of the first plurality of fluid channels is in fluid communication with the second inlet of a second sub-plurality of the second plurality of fluid channels.
