Abstract
A rotary valve includes a valve body defining an inlet, an outlet, and a fluid flow path connecting the inlet and the outlet, and a valve shaft is disposed in the valve body. A control element includes a first side, a second side, and defines a pivot axis. The control element operatively connected to the valve shaft, disposed in the fluid flow path, and is rotatable by the valve shaft about the pivot axis between an open position, in which the control element permits fluid flow between the inlet and the outlet, and a closed position, in which the control element limits flow between the inlet and the outlet of the valve body. A portion of the control element includes a lattice structure including a plurality of connected lattice members. The lattice structure defines one or more channels extending across the first side of the control element.
