2-component (K) dosing valves 

Dosing heads for applying glue, potting, thermal paste... 

Our 2k electrovalves are ideal for the precise dosing of two-component materials from 2k double cartridges. Spindle motors have the advantage over pneumatically controlled valves that the pistons can be moved continuously and precisely.

The mixing ratio is achieved via the geometry of the cartridges. The mixing ratio is limited to
M1:1, M1:2, M1:4 and 1:10 . There are double cartridges with a capacity of 50 ml, 200 ml, 400 ml .

With the 2-component dosing valve for dosing from 2-component DUO cartridges, a spindle pushes 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. The folding mechanism makes it easy to change the cartridges. Parameters such as dosing quantity, dosing speed, etc. can be entered via the controller.

The use of electrical volume dosing makes sense when media with high volume accuracy have to be applied. The flow rate can be fixed. This set quantity is dosed. The dosing takes place evenly and independently of the filling quantity.

Some of our 2K valves have a heater for the mixer or valve head. In this way, media can often be dosed better and more easily by increasing the temperature.

A simple and inexpensive way to heat the material in the mixing tube is to use a mixing tube heater.

2-component casting compounds are usually low-viscosity, i.e. very liquid, so that they can flow well into gaps. This can be problematic because the dosing medium often continues to flow even though dosing has already stopped.
In this case, the shut-off valve closes the outlet of the mixing tube via a small shut-off cock. Only this comes into contact with the 2k material and can be easily replaced.

  • Can be used for media with low to high viscosity

  • Flexible quantity setting - Even material flow

  • No dripping due to adjustable retraction

  • Parameters adjustable via machine or controller

  • Easy to integrate into robot and axis systems 

 
 

2-component 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. Parameters such as dosing quantity, dosing speed, etc. can be entered via the controller .

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.
