One of the major advantage of the SoliValve® system in comparison with its Cone Valve ,Split Butterfly Valve, Iris valves and dosing screw competitors is its metering and dosing accuracy.

Standard Cone Valve and Split Butterfly Valves don't allow precision dosing. Dosing screw offers better results but the accuracy is limited by the size of the "chamber", defined by the pitch and the diameter of the screw.
The SoliValve® 100 opening control has an accuracy of 0.1mm (1mm for the SoliValve® 250), allowing much more metering precision.


In combination with the dedicated control software and dosing algorithm, the SoliValve® technology allows very accurate and repeatable dosing thanks to a ball screw drive system positioning the Cone Valve opening accurately during the whole discharging sequence, helped by a very efficient high frequency internal vibrator.

Not only allows the SoliValve® system a precise dosing, but a controllable discharge speed as well.

With a user friendly Touch Panel interface, different discharge parameters (or recipes) can be selected for each products, depending on their flow-ability and desired dosing accuracy.

The dosing algorithm has many adjustable parameters to allow the operator to reach his dosing accuracy for each powder. The in flight weight value is taken in account when the SoliValve is closing in order to achieve maximum accuracy.

All dosing are saved on an SD card in the Siemens CPU and can be easily exported in an Excel sheet, either directly from the USB connection of the Panel or through the Network. The whole production can be traced.

In order to benefit from the dosing capability of the SoliValve®, the system needs either to be mounted on load cells or used together with a floor scale.

Contact us for a dosing test trial with your powder in our workshop.


SoliValve dosing accuracy:

The dosing accuracy of the SoliValve 250 reaches values of +/- 20g.

The dosing accuracy of the SoliValve 100 reaches outstanding values of +/- 1g!

Note: these are typical values. A test trial with your powder in our workshop is recommended in order to validate the accuracy.
