CORA® Rotary Dosing Valve RV-SR

Multi-vane, rotary dosing valve for accurate dosing of powders and granulates.

The CORA® RV-SR Rotary Dosing Valve is a solution designed for accurate dosing and consists of two concentric rotors of different volume individually operated, which determine product flow and dosing. The main rotor ensures continuous product flow while the secondary rotor ensures accurate dosing.  The CORA® RV-SR is typically used in feeding packaging machines, drum & bag filling systems, and for dispensing.
