Our Electro-valve as a 2K-dispenser head is highly suitable for electronical precise dispensing of Two-components media out of 2K-double cartridges - the problems of pneumatical controlled valves are avoided that can´t achieve the precision of step-motors.
The media of those double-cartridges are mixed in a static mixing tube according of relevant ratios.
The geometry of the double cartridges hereby determines the mixing ratio.
By now the cartridges are offered in mixing ratios of 1:1, 1:2, 1:4 und 1:10, where the special size (e.g. 50 ml) only can be dispensed with the according valve (here Art.No. 4042 E50).
By using 2-component cartridges you can avoid the partly problematic handling of certain media that hardening time after mixing can be situated in a few minutes only.

The deployment of a 2K-gear pump is useful for all operations you have to dispense 2K-media out of 200 ml or 400 ml DUO-cartridges with high volume accuracy.
Two separate gear pumps are operated with a single motor by connection shaft.
The mixing ratio is determined by pump volume, so there are three mixing ratios possible.
The discharging of the pump can be set.
The pre-set volume will be dispensed, then the gear pump is automatically stopped.
It also can be switched on and off with an external pushbutton.
Volume dispensing of low to high viscous media by eccentric screw.
Material protecting charging with a volume accuracy of ca. 1%
Suitable for dispensing of UV-media, silicones, glues, greases but even abrasive media.
