Description
Bürkert's unique type 0127 solenoid valve is the pioneer of the medium-separated small valves and is predestined for use in laboratories, medical and analytical technology. With its rocker technology, which operates the separating membrane between drive and fluid, it sets new standards today. It ensures precise switching of the smallest volume even aggressive media with a minimum temperature input through the coil. In addition, it is very easy to rinse and is characterized by a minimum internal volume and virtually no dead space. The valves can be connected in series on connection plates and can be wired with central wiring upon request. Special low-dead space versions are available on request.
