Fine Dosing


This valve is an alternative to the Rotodoser valve (our fast feed and fine dosing valve), which shares with Rotometering an important part of its design: it consists of two coaxial dosing parts (actuated independently), which determine flow of the product and its dosage.
While in both valves the main rotor ensures flow control, Rotometering precise dosage is no longer volumetric (entrusted to a mini rotor that discharges pocket after pocket as in the Rotodoser), but gravimetric (made by an open auger screw -or hydraulic screw- that guarantees continuous flow). In addition, as the auger screw is open, it will allow easy cleaning during maintenance procedure.

Rotodoser is the solution designed for accurate dosing. It consists of two concentric rotors of different volumes individually driven that determine the flow and dosage of the product. The main rotor guarantees a continuous product flow, while the secondary rotor guarantees a high precision dosage. Rotodoser by Sterivalves is a valve designed to guarantee high versatility, in fact rotors are also customizable.
