Müller Containment Split Butterfly Valve

Exploded Drawing: Split Butterfly Valves

Powder handling OEB Level 3 - 5

At last a stable and robust split butterfly valve system for emptying and filling your highly potent or toxic media. Light to handle and safe to use. You can rely on the Müller Containment Valve to safeguard the health of your employees even as you maintain the purity of your product and protect the environment.

The Müller Containment Split Butterfly Valve MCV is in two halves: the active and passive disks. The active disk incorporates the mechanical system for locking both halves together and a manual lever or actuator for opening and closing the valve. The active half of the valve is fitted to the vessel filling or emptying nozzle, and the passive half to the intermediate bulk container. The two halves of the butterfly valve (active and passive disks) must be docked together in order to open the valve. The ruggedly constructed and GMP-compliant locking device ensures accurate location and the safe docking when the two halves are connected. When both halves of the valves are locked together, the system is closed to the atmosphere and the valve can then be opened – manually or automatically, whichever way you prefer.

By adopting the Müller Containment Split Butterfly Valve MCV in your production processes, you ensure your staff's health and that the product stays 100% pure.

The valve system can be cleaned quickly and simply, thus reducing production line downtime. A valve disk can be replaced in less than two minutes.

Ingenious details make a perfect solution: The Mueller Containment Split Butterfly Valve (MCV)

Whether operated manually or automatically, the Mueller Containment Valve ensures that your toxic or highly potent products transfer safely – from the intermediate bulk container into the process line and back into a container again, exactly how you want it. And all this up to OBE Level 5 (SMEPAC), i.e. up to OEL < 1 μg/m3. You can choose between valve sizes DN100, DN150, DN200 and DN250.
