Dosing screws offer good and repeatable accuracy but are limited by the size of the "chamber", defined by the pitch and the diameter of the screw. It means that a dosing screw is usually ideal only for a defined range of weight and speed. For large weighing range, 2 or more sizes of screws would be needed. Furthermore, the dosing screw is not a containment device and its cleaning is a complicated task as the screw must be dismounted to gain acces to the auger.
The SoliValve® controls its opening to an accuracy of 1mm (0.1mm for the SoliValve® 100), allowing high dosing accuracies for a wide weighing range, from few hundred grams to over 1'000kg.
The SoliValve®250 is designed to be used with IBCs, FIBCs and drums from 25 up to 1'500kg.
The SoliValve®100 is designed to be used for active ingredients, vitamins and highly potent API's. These types of powders are usually stored in smaller size recipients, from <1kg to 50kg. Some applications see the SoliValve®100 being used on larger IBCs/hopper and big bags up to 1000 Litres.
Key Benefits of the SoliValve® Cone Valve technology:
SoliValve® is the answer to the limitations of all conventional docking systems currently available on the market. It is designed to be used with IBCs, FIBCs, drums and pouches from <1kg up to 1'500kg.
