Pneumatic Conveyors

Kongskilde’s pneumatic rotary valves, including the CAD and CAE models, provide a sophisticated solution for introducing grain into pneumatic conveying systems. 

These valves facilitate the efficient movement of grain along pipelines in both pressure and suction conveying systems, optimizing the transfer process with precision and reliability. 

Designed for larger capacities, the CAD and CAE rotary valves enhance system performance and are critical components in modern agricultural and industrial operations.

How Kongskilde Rotary Valves Work

Kongskilde rotary valves operate by utilizing a motor-driven mechanism that rotates polyurethane or rubber paddles to regulate the flow of materials into conveying systems. These valves act as airlocks, maintaining the necessary pressure differential in the system, which is essential for the continuous and controlled discharge of materials from cyclones or filter units into the conveying line. This method significantly increases the capacity over simpler solutions like injectors, making it suitable for handling larger volumes of material efficiently.

Benefits of Kongskilde Rotary Valves

• Increased Conveying Capacity: Designed to handle large volumes, these valves ensure a smooth and continuous flow of materials.
• Air Loss Prevention: Equipped with rubber paddles that provide an excellent seal, minimizing air loss during operation.
• Low Maintenance: The valves are constructed with durability in mind, requiring minimal upkeep thanks to wear-resistant materials.
• Clog Minimization: Rubber paddles are flexible, which helps to prevent material clogging and ensures consistent operation.
