The MD-200 (medium-duty) dosing valves are especially built and tested for dosing- and pneumatic conveying of powders and granulates. The modular building concept allows us to use “of the shelf” parts, which are combined to a customized solution within the shortest possible delivery time.
MD rotary valves can be used in installations with differential-pressures up to approx. 1 bar.
In- and outlet are designed for optimal filling and low resistance, resulting in less wear to the valve, and less damage to the conveyed product. The use of external ball-bearings, adjustable gland packings and a direct drive ensure optimum maintenance-friendliness.
