Slim, fast, precise, robust, cost saving and easy to clean – this is in brief the flipper solenoid valve type 6650 (FSV 6650) from Bürkert. This media-separated valve is a fast-switching valve for reproducible and precise dosing for chemically aggressive fluids. Due to its slimness of 4.5 mm the FSV 6650 allows equipment and instrument manufacturers to pack more valves into the same space for greater functionality, or helps reduce laboratory costs by shrinking the size of the equipment or instrument. The flipper valve’s optimised internal design leads to a low internal volume and enables effective flushing of materials through the device such as formerly known in rocker valves only. The flipper technology is based on an elastomer element that moves between two opposite valve seats and opens or closes one of them. The common port can be used as inlet to distribute to one of the valves seats or as mixer vice versa. The FSV 6650 options include 2/2-way and 3/2-way configurations, as well as two different orifice sizes. In combination with the 0.4 mm orifice and the normally closed function it allows for a pressure rating up to 7 bar. With body material PEEK and seals made of FFKM, the valve can be used for a wide range of aggressive fluids.
