With a pitch of only 4.5 mm, Bürkert's 6650 flipper solenoid valve is available in a 2/2 and 3/2 way version. This extremely compact and fast switching valve has been optimized for reproducible and precise dosing of aggressive fluids in analytical applications requiring maximum fluidic capacities in a compact space. Its technology is based on an elastomer element which moves between 2 opposing valve seats, opening one and closing the other. The common connection can be used as an inlet for distribution to one of the two seats or as an outlet for a mixer function. The media only comes into contact with the housing, made of PEEK, and the seal elements, made of FFKM.
