A rotary valve is a critical component used in pneumatic conveying and bulk material handling systems for the controlled feeding and discharge of powders, granules, pellets, and other dry bulk materials. These valves are widely used in industries such as cement, chemicals, food processing, pharmaceuticals, plastics, mining, and power generation where maintaining smooth material flow and pressure balance is essential. Designed for continuous industrial operation, rotary valves help reduce air leakage, improve conveying efficiency, and ensure accurate material transfer within processing systems.
