Over the course of their long existence solenoid valves have developed slowly but continuously so that they are opening up new fields of application. Today they are a central element in controlling fluids in a broad spectrum of different applications. One of the newer areas of application is in the life sciences. 17 years ago the media separated valve type 0127, with its pressure equalized, long-life and flushable rocker technology, set a milestone in the field of small media separated solenoid valves for life science applications. In 2011 Bürkert set another milestone with the new TwinPower actuation technology, which allows a significant reduction in size with no loss of performance. This resulted in the Type 6624 and 6626 valves, which feature high flow rates and a compact design in combination with the time-tested and further optimized rocker technology.
