  • Publication number: 20240133472
    Abstract: 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.

  • Publication number: 20230358321
    Abstract: Fluid management systems for handling pressurized fluid connect various subsystems or subunits without the need to use reinforced tubing. The system utilizes one or more segments of unreinforced conduit that are encapsulated at various points along a length of the segment with one or more rigid encapsulating members. The unreinforced conduit may be made a disposable element while the rigid encapsulating members may be re-used. In one aspect, the encapsulating member may include a two-part valve body that surrounds and encapsulates a portion of the unreinforced conduit. In another aspect, the encapsulating member may include a two-part jacket that surrounds and encapsulates a portion of the unreinforced conduit. The two-part valve bodies and two-part jackets may be joined at various points within the system as part of the overall flow system.

  • Patent number: 11719348
    Abstract: An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.

  • Publication number: 20230211292
    Abstract: Vessel configured to facilitate concentration of a product in a solution. The vessel may include outlet ports to deliver the solution to a processing system (such as a filtration system), and inlet ports. The inlet ports may be at progressively lower levels for return of fluid thereto reduced in volume as a result of filtration thereof. A smaller volume sump may be provided below a main tank of the vessel to facilitate concentration of the solution. The sump may include ridges facilitating collection of the product of interest from the solution, and/or reinforcing the sump walls, and optionally forming a vortex breaker. A spray ball may be provided to spray materials, such as buffer solution, into the vessel. The spray ball may direct materials to facilitate retrieval of product from the vessel. One or more components of the vessel may be advantageously formed of disposable material for single use thereof.
