International valve specialist GEMÜ is expanding its single-use range with the GEMÜ Multiport SUMONDO multi-port valve block, which is available with pneumatic or manual block locking.

The GEMÜ Multiport SUMONDO combines several individual single-use diaphragm valves in one multi-port valve block, offering a new solution for applications in pharmaceutical and biotechnological industries.

The “tried-and-tested” GEMÜ SUMONDO diaphragm valve principle ensures hermetic separation between the actuator and the medium by welding the diaphragm to the body. When using the GEMÜ Multiport SUMONDO, the actuator unit remains permanently installed in the plant, while the M-block is replaced after use.

The compact M-blocks, which do not require tubes or piping between two seats, have a low hold-up volume compared with single valve solutions. This leads to greater process reliability and efficiency. Additionally, less space is required in the plant, owing to the compact design.

Production in accordance with Good Manufacturing Practices standards also ensures that the media wetted single-use M-blocks meet the highest standards in terms of purity, safety and stability.

Pneumatic or Manual Block Locking

Two block locking options are available, which differ in the way the M-block (disposable) is connected to the actuator unit and offer either pneumatic locking or manual locking using a hand lever. Both versions enable simple operation and fast replacement of the disposable between different production cycles.

The milled disposables can be manufactured in various designs, with different connections and sensor integrations for targeted use in the upstream and downstream area. This means that the M-blocks can be customised and implemented according to customer requirements.

Since 1964, the GEMÜ Group has been developing and manufacturing valves, measurement and control systems for liquids, vapours and gases. The company is a global market leader when it comes to solutions for sterile applications.

In addition to the two production sites in Germany, GEMÜ manufactures its products in Brazil, China, France, India, Switzerland and the US.

GEMÜ is active in more than 50 countries on all continents through a dense network of trading partners.
