Abstract
A valve unit for dosing fluids is specified, which has a fluid housing including a valve seat, a fluid channel, which extends from a fluid inlet to the valve seat and from the latter to a fluid outlet, a movably mounted valve closing body for controlling or regulating a flow through the fluid channel, and a first electrode and a second electrode, wherein the first electrode is arranged in the fluid channel upstream of the valve seat and the second electrode is arranged in the fluid channel downstream of the valve seat, wherein a distance of the two electrodes from each another is at most 3 mm and/or a maximum distance of the individual electrodes from the valve seat is at most 1.5 mm. Furthermore, a valve assembly and a method of checking a closed state of a valve unit are specified.
