Rotometering valve

The need for precision dosing of a product is one of the most frequent request we receive from pharmaceutical and food industries. Sometimes it is necessary to divide a batch into smaller containers or packages; other times it is essential to add an ingredient to a recipe with extreme precision and speed.

In recent years our R&D department has paid special attention to this aspect, dedicated and commited to meet this growing demand. In this way we have created a new advanced solution capable of guaranteeing even greater dosing precision, speed and flexibility: the Rotometering valve.

How is it composed?

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.

How Does It Work?

The main rotor discharges the product at 180 ° in the reciprocating motion; while fine dosage is carried out by the internal auger screw that rotates at 360 °.

What are the main advantages?

Its sanitary design
Allows to reach the target with greater precision and flexibility.
Particularly suitable for processes where product does not flow easily: the auger screw movement allows the product to be physically transferred, favoring dosing.

What are its main applications?

Ideal for weighing and packaging machines, feeding of hoppers.
