Patented Flipper Technology Enables New Miniature 3/2 Isolation Valve to Set New Benchmark in Analytical & Biomedical Tasks.

The Type 6650 provides the ideal solution for manufacturers with valve applications requiring fast response times, high reproducibility, zero pumping and excellent flushing characteristics. The valve’s optimised design ensures reproducible and precise dosing, effective rinsing capability, and is suitable for use with aggressive chemicals.

Key to the performance of the Type 6650 valve is Bürkert's patented Flipper Technology. This employs an elastomer element which moves between two opposite valve seats under the force of permanent magnets fixed to the flipper element; opening one as it closes the other. This operation requires only a temporary pulse, so is characterised by its short response time. It also provides benefits in terms of high reliability and very low levels of wear.

With the two nominal sizes 0.4mm and 0.8mm available, and both 2/2 and 3/2 functionality, the Type 6650 is ideal for applications where the highest fluid performances are required in the smallest space – in dosing for example where the Type 6650 opens up new possibilities, in particular, in connection with 384-well Microtiter plates.

The Type 6650 is ably equipped for use in its target markets; both the new 3/2 valve and the 2/2 variant, which was launched in 2008, have bodies manufactured from high performance PEEK and seals made of FFKM.
