Rotovalve Light is the rotary valve by Sterivalves designed for pharmaceutical, chemical and food industry. Rotovalve Light is assembled in order to be dedicated to feed and control in a continuous way the unloaded flow, without losing its qualities in the long term use. Thanks to the alternating rotary movement, the valve favours the homogeneous unloading of the product, allowing a high precision production, without any waste neither of raw materials nor of the finished product.

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
