Abstract
A valve assembly may include a valve body, a valve member, and a valve shaft. The valve body may include an inlet, an outlet, and first and second fluid paths in fluid communication with the inlet. The first fluid path may extend axially through at least a portion of the valve body. The second fluid path may be defined by first and second annular walls and may at least partially surround the first fluid path. The valve member is disposed in the valve body and may be movable between a first position preventing fluid flow through the first fluid path and a second position allowing fluid flow through the first fluid path. The valve shaft may be fixed to the valve member and mounted to the valve body for rotation relative to the valve body.
