GEMÜ has expanded its new generation of valve products with the launch of the D20 manual diaphragm valve, developed for hygienic and aseptic applications in industries requiring high standards of cleanliness and process reliability. The GEMÜ D20 is designed for sterile service and is suitable for applications meeting 3-A requirements. The valve is intended for use in sectors including food and beverage processing and pharmaceuticals, where hygienic design and reliable separation of process media are essential.
The new valve features actuator components made primarily from stainless steel, with the exception of sealing and design elements. Its firmly chambered diaphragm provides hermetic separation between the actuator and the working medium. This design is intended to ensure reliable sealing without the need for subsequent tightening during operation.
The D20 also features a sealed handwheel design that supports compliance with 3-A hygiene requirements. The product has been developed to combine hygienic construction with simplified operation and maintenance for demanding sterile processes. A key feature of the valve is its newly developed diaphragm technology. The diaphragm uses a bayonet pin connection, allowing it to be replaced quickly and helping reduce susceptibility to faults. This design can simplify maintenance procedures and reduce the time required for servicing.
The valve is also equipped with a scaled optical position indicator, allowing operators to check the valve position at any time. The feature provides a clear visual indication during process operation. GEMÜ has designed the valve body with flow optimisation in mind. The D20 achieves high Kv values and is intended to provide high flow capacity and homogeneous flow characteristics. These features can contribute to improved process performance in applications where efficient media handling is required.
The valve is suitable for cleaning-in-place and sterilization-in-place processes and can also be autoclaved. These capabilities make it suitable for applications requiring regular cleaning and sterilisation without extensive dismantling of equipment. At launch, the GEMÜ D20 is available in diaphragm size MG B. The company plans to introduce additional diaphragm sizes as the product range is expanded.
The D20 becomes part of GEMÜ’s wider new generation of valve and automation products. The range already includes the D40 pneumatic diaphragm valve, the D41 diaphragm valve with EasyLock technology, the S40 globe valve, the P40 tank bottom valve, the 12A0 electrical position indicator and the 44A0 combi switchbox.
With the addition of the D20, GEMÜ is further expanding its portfolio for hygienic and sterile processing environments. The new manual diaphragm valve offers a combination of stainless-steel construction, hermetic separation, simplified diaphragm replacement and cleaning and sterilisation capabilities for food, pharmaceutical and other high-purity applications.
