Thanks to the patented Bürkert flipper technology, the direct-acting 6604 Envelope Dimensions [mm] (see datasheet for details)
solenoid valve is unique. It combines fast, precise switching behaviour
with reliable media separation, and the design eliminates heat transfer Flange connection
between fluid and coil. The use of high quality materials makes it possible
to also use it where high chemical resistance is required. The optional im-
pulse model works with the smallest energy requirement, and is therefore
especially suitable for battery operation; the heat transfer to the medium D
is negligible for this model. A minimal dead volume and gap-free internal
design make it possible to use it in medical, analytical and laboratory
technology.
