The ProFi-Accurate dosing valve is a compact system designed for the gentle and precise dosing of solid products. A uniform and clog-free product flow is thus ensured.
Thanks to its compact construction, the stand-alone ProFi-Accurate dosing valve is easily integrated in Frewitt units or in the customers’ existing process plants.
The valve is actuated by a servomotor, which effectively prevents the formation of product bridges in the vibration or oscillation mode.
