The Rotoflexi valve is dedicated to the feeding of fragile products such as capsules, tablets, beads and all those elements that can be easily damaged by the movement of a steel rotor. In fact, the silicone coating allows for greater sensitivity of the rotary component. Moreover, unlike traditional systems, the structure and assembly of Rotoflexi allow easy cleaning, as well as very simple maintenance. These features ensure that the installation of our valve significantly optimizes the operation of the entire plant, with beneficial consequences on the entire production process.

Our valves are designed for each component to interlock with one another perfectly, creating a gapless match, and preventing the product from storing within, therefore averting product cross-contamination.

From metal powder to the delivery of the final product, we trace and document all events associated with each part and component, to provide full traceability for all our products. This is particularly important in the pharmaceutical and food industry, to assure the quality of production lines and trace down possible issues to quickly intervene and solve related problems.



Easy assembly and disassembly

No-tool installation and assembly

Reduces risks of external contamination

Reduces cleaning time
