Burkert’s new FSV 6650, a flipper solenoid valve, is the newest addition to the company’s valve family. With this media-separated valve, Burkert offers a fast-switching valve for reproducible and precise dosing of chemically aggressive fluids. The new flipper valve, with an optimised internal design, leads to a low internal volume and enables effective flushing of materials through the device, formerly known in rocker valves only. 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 common port can be used as inlet to distribute to one of the valve 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 0.4mm orifice and the normally closed function it allows for a pressure rating up to 7bar. With body material PEEK and seals made of FFKM, the valve can be used for a wide range of aggressive fluids. Furthermore the FSV 6650 provides IP65 protection, qualifying it even for rough environments.
