Specifications
Two compartments are filled with product through the spout at the top. After less than a half turn, the rotor discharges the product by gravity into the current generated by the compressed air that passes through the lower part of the rotary valve. The product is thus transferred. It is connected by flanges to the pneumatic piping at the two ends. The in-line connection of the rotary valve on the pneumatic piping ensures the speed setting of the product. A degassing line may be connected to the valve body to balance the volumes and ensure optimum filling.
