Split butterfly valves ensure the protection of both people and products when charging and discharging highly potent APIs.
The docking system comprises two half valves that are able to independently seal two different containers. A corresponding actuator ring is used to lock and activate the two half valves, which then allows contained powder transfer.
Undocked and Closed
When undocked and closed, the half valves prevent any product from leaving the container to contaminate the surrounding environment.
Docked and Closed
When docked and closed, the half valves are sealed and connected.
Docked and Open
Both half valves now operate as a single butterfly valve and product can be discharged in a fully contained way.
The BUCK® MC Valve builds on the proven design principles of the first generation of split butterfly valves and offers a number of key additional features and benefits:
GEA has a long history of expertise and an unparalleled depth of experience in the field of containment. We offer a wide range of technologies and equipment that improve and enhance the efficiency and performance of solid dosage form plants for the safe transfer of powders.
The actuator ring is available in three different versions:
A single portable actuator ring can be used to manually dock several vessels in the same room or charge/discharge numerous pieces of equipment.
Fixed actuator rings (manual or pneumatic) can be attached to and used with hoists, forklifts, pallet trucks, etc. All sensors are enclosed within the actuator ring, and all cables are contained in a single, central gland.
All our actuator rings offer quick, tool-free removal of the half valve as standard. And, there's no need to disconnect any utilities for maintenance.
The BUCK® MC half valve forms the basis of the docking system. It is the only product contact part and comprises a housing, main body seal, disc seal and a fixed bearing disk. For an active station (fixed actuator ring), the half valve is integrated into the actuator unit and has a flexible connection. For manual and mobile applications, the half valve is mounted directly on the process unit. The second half valve is connected to a mobile container.
All wash equipment is affixed to a wash half valve.
The BUCK® MC Lite DN100/150 from GEA is the first lightweight split butterfly valve for the contained transfer of highly potent solid dosage products.
Containment issues are becoming an increasingly important aspect of solid dosage form production, especially for highly potent and toxic active pharmaceutical ingredients (APIs) for hormone and oncology applications.
With a more intense focus on health and safety, avoiding both operator exposure and preventing cross-contamination is critical. For contained solid powder transfer, the solution is BUCK®.
Based on the success of the BUCK® MC (modular containment) valve, GEA is taken a bold step forward and further enhancing the ease of use and convenience of its DN100/150 actuator ring.
The new BUCK® MC Lite portable actuator ring retains the key advantages of the original MC actuator ring, including free orientation during docking, fast product changeovers, simple operation, maintenance and cleaning, and also comprises identical half valves for both sides of the docking station. In addition, the same unit can be used to dock several different processes. It’s also compatible with existing BUCK® MC half valves.
Offering the same functionality as the previous version, GEA has succeeded in making the actuator ring even more compact and lightweight. It weighs just 3.3 kg, which makes the entire unit easier to handle and implement. GEA has the health and welfare of your operators in mind, not to mention process optimization and productivity.
Offering standard and customized solutions, GEA’s split butterfly valve portfolio includes both manual and automated BUCK® MC valves (DN100–250) with optional assemblies (weighing, raising/lowering and compensator devices), suction for high containment applications (<1 μg/m3 STTWA) and total containment (TC) valve technologies. In addition, the Hicoflex® disposable bag and interface system allows visible product transfer and is designed to handle highly potent solids at volumes of 1–50 L.
