- F or highest chemical resistance requirements Ultr a compact design due to Bürkert TwinPower actuator with 16 mm width/station DN 2.0 (3 bar) and DN 3.0 (2 bar) Int egrated hit-and-hold electronics assembly High back-pr essure tightness with excellent cleanability From the fluidics perspective, Type 6626 combines the reliable and success- ful rocker principle. Due to the new Bürkert TwinPower concept, this actuator enables drastic reduction of installation space while maintaining performance output. Hence, the 16 mm wide medium separated rocker valve, with 3.0 mm DN and a pressure resistance of 2 bar, provides the same performance as a traditional 22 mm valve. In addition, the integrated power reduction decreases energy consumption by 75 %. In combination with other design featur es, the heat transfer into the medium can be reduced to a minimum. With regard to the design, special attention has been placed on excellent cleanability and high reliability. By using high quality materials, Type 6626 is also ideal for handling aggressive medium. The valve is available as a 2/2 way and 3/2 way version. Product variants described in the data sheet may differ from the product presentation and description.
