Valve assembly with directional flow path
A valve assembly with a multidirectional flow path includes a valve body that includes respective hinged portions defining respective passageways extending through the valve body when in a closed state. A flexible conduit or tubing having a loop portion and a plurality of branches extending from the loop portion is at least partially positioned within the valve body. Portions of the loop that extend beyond the valve body are encapsulated by respective rigid jackets. Multiple valves are situated on the valve body and are used to selectively pinch the loop portion in different pinching configurations to direct fluid to or from the particular branches. The valve assembly may be integrated into a manufacturing or other production process with optional additional jackets used to encapsulate the flexible conduit branches.
