The FSV 6650 miniature valve, the new member of the Burkert valve family, is an ultra slim and ultra quick flipper solenoid valve. The valve offers a fast-switching valve for reproducible and precise dosing of chemically aggressive fluids. Due to its 4.5mm width 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 new flipper valve, with an optimised internal design, leads to a low internal volume and enables effective flushing of materials through the device. This in essence increases the utilisation of the media used, eliminates the waste of expensive reagents as well as cross contamination and raises process safety. The Burkert patented flipper technology is based on an elastomer element that moves between two opposite valve seats and opens or closes one of them. The FSV 6650 options include 2/2-way and 3/2-way configurations, as well as two different orifice sizes. In combination with the 0.4mm orifice and the normally closed function it allows for a pressure rating up to 7bar. Furthermore the FSV 6650 provides IP65 protection, qualifying it for rough environments.
