EBRO Impeller valves are used in powder and bulk material processes to discharge materials in a smooth, continuous manner. Impeller valves discharge powder from silos, hoppers and big bags to the next production step of weighing bins, reactors and screw conveyors. They eliminate your typical problems of clogging, coagulation, compressing and sticking. In addition, impeller valves keep the crushing of granules, pellets and flakes to a minimum.
The impeller wheel is globe shaped and the body is cylindrical inside. There is no scratching of the product on the body wall or product travelling into the bearing or sealing.
Impeller valves have 6 blades (three pairs). Since the inlet geometry is full bore the diameter of the pipe above the impeller valve, the impeller valve can rotate with more than twice the speed of a rotary feeder. The blade can be stopped in the middle of the body with one pair of blades safely sealing. There is no “dead zone” inside, where the product could stay after the valve is stopped.
