Gear pump and cartridge spindle valve
The use of electric volume dispensers makes sense when media with high volume accuracy have to be applied. The flow rate can be fixed. A set quantity is dosed. The dosing takes place evenly and independently of the filling quantity. They increase the process reliability of dosing enormously.
Der Einsatz von elektrischen Volumendosieren ist sinnvoll, wenn Medien mit hoher Volumengenauigkeit aufgetragen werden müssen. Die Fördermenge kann fest eingestellt werden. Diese eingestellte Menge wird dosiert. Die Dosierung findet gleichmäßig und unabhängig von der Füllmenge statt. Einige unserer 2K Ventile verfügen über eine Heizung für den Mischer bzw. Ventilkopf. So lassen sich Medien über eine Temperaturerhöhung oftmals besser und leichter dosieren.
Eine einfache und günstige Möglichkeit, das Material im Mischrohr zu erwärmen, ist die Anwendung einer Mischrohrheizung.
2K-Vergussmassen sind in der Regel niederviskos, also sehr flüssig, damit diese gut in Zwischenräume fließen können.
Dies kann problematisch sein, da das Dosiermedium oftmals weiterfließt, obwohl die Dosierung schon gestoppt wurde.
In diesem Fall schließt das Absperrventil den Ausgang das Mischrohrs über einen kleinen Absperrhahn. Nur dieser kommt mit dem 2K-Material in Berührung und kann problemlos ausgewechselt werden.

2K electrovalves
For dosing glue and applying thermal paste.
Electric valve for dispensing from 2K DUO cartridges. The spindle motor presses out components A and B in parallel via guided linear rods. The material in the cartridge is relaxed via a retraction and thus prevents dripping. About thesteeringparameters such as dosing quantity, dosing speed, etc. can be entered.
2K electrovalves
with heating
2k dosing with 2K electrovalves and heating for applying two-component media.
Electronically precisely controlled dosing from 2K double cartridges for materials that can be heated to enable or improve dosing ability.

2K volume dosing
The 2K gear pump is used when 2K media with high volume accuracy have to be applied from 200 ml or 400 ml DUO cartridges. Two separate gear pumps are driven by a single motor via a connecting shaft.
The mixing ratio is determined by the pump size, resulting in three possible mixing ratios. The flow rate can be adjusted. A specified amount is dosed, then the gear pump switches off automatically. It can also be switched on and off via an external switch.
