Rotary valve operation during material handling

Although rotary valves are small parts in big steel plants, they play an important role in the material flow process which is vital for uninterrupted steel making. Discharging lump raw materials, dust or ash from silos, bunkers and hoppers or take-over points in conveying systems are typical locations for rotary valves. For proper functioning of all system parts, it is important to monitor the operation of the valve via axle movement control using inductive sensors or encoders.
