Rotovalve Light
The SteriValves Rotovalve Light is a rotary butterfly valve specifically engineered for the pharmaceutical, chemical, and food industries. With its alternating rotary movement, it ensures homogeneous product discharge, optimizing flow and guaranteeing continuous and precise downstream process feeding.
Designed to simplify assembly and disassembly, this valve complies with cGMP (current Good Manufacturing Practices) and international standards for the safe handling of pharmaceutical, chemical, and food products.
Rotovalve Light is the ideal solution for dosing bulk materials and feeding machinery, offering maximum efficiency, safety, and compliance with ATEX certifications, Regulation (EC) No. 1935/2004, FCM (Food Contact Materials), and FDA standards.

Product properties
Application
- Bottom valve for discharging hoppers, mixers, and other equipment.
- Feeding tablet presses, homogenizers, and equipment for fractioning and dosing powders or granulates.
Function
Rotovalve Light enables precise flow control thanks to its alternating rotor motion, effectively interrupting and dosing material. This technology:
- Prevents bridging or channeling.
- Facilitates homogeneous discharge even of cohesive powders or fragile mixtures.
- Avoids clogging, simplifying the handling of bulk solids when transferring between units.
Solution
Rotovalve Light effectively addresses situations where traditional butterfly valves or continuous rotary valves cannot guarantee:
- Precision in batch or continuous dosing.
- Adequate sealing in the presence of fine powders (using the Beta rotor version).
- Durability in demanding operational conditions (using the Alpha rotor, which reduces seal wear).
- The alternating rotary movement ensures uniform and controlled discharge.
Advantages and Customer Benefits
- Compact design → Ideal for installations with limited space.
- Easy maintenance → Simplified design for quick disassembly and cleaning.
- Minimizes product losses → Reduces waste and enhances production efficiency.
- Optimizes processes → Enables precise feeding, improving plant performance.
- Reduced operational costs → Increased efficiency and fewer downtimes contribute to lower management costs.
