Efficient, Precise, and Durable: Discover KREISEL Rotary Valves in Action
This video introduces you to the innovative rotary valves developed by KREISEL GmbH & Co. KG, a leading German manufacturer specializing in high-performance components for bulk material handling systems.
Rotary valves are essential for accurate dosing, safe discharge, and controlled feeding of powders and granulates - especially in pneumatic conveying systems. KREISEL’s engineering excellence ensures these components are precise, durable, and adaptable across a wide range of industries and applications.
What Are KREISEL Rotary Valves?
Rotary valves by KREISEL are designed to regulate the flow of bulk materials from silos, bins, filters, or pneumatic conveying lines.
The rotor inside the valve rotates to transfer a measured volume of material from the inlet to the outlet, all while minimizing air leakage. This makes them ideal for volumetric dosing and reliable pressure separation between different stages of processing.
Versatile Applications Across Industries
Rotary valves are critical wherever powders or granular materials need to be fed, discharged, or dosed precisely. As demonstrated in the video, KREISEL rotary valves are used in:
- Pneumatic conveying systems – feeding bulk solids into pressurized pipelines
- Dust collection systems – discharging fine particles from filters or separators
- Silos and hoppers – providing continuous, consistent discharge of stored materials
- Mixers, dryers, and reactors – enabling accurate material input in batch or continuous processes
They serve industries such as cement, chemicals, power plants, pharmaceuticals, and food production - all requiring precision, cleanliness, and reliability in material handling.
Product Variants for Specific Requirements
KREISEL offers different rotary valve types to suit a variety of handling challenges:
- Standard Rotary Valves – The universal solution for dry, free-flowing bulk solids
- Clearing Rotary Valves – Equipped with clearing blades for sticky, moist, or poorly flowing materials
- High-Pressure Rotary Valves (RotoFeed®) – Specifically engineered for injecting materials into dense-phase or high-pressure pneumatic systems
Each model is designed with application-specific features, such as wear resistance, heat resistance, or food-grade certification.
Technical Highlights
KREISEL rotary valves are engineered for long-term use in challenging industrial conditions. Key technical features include:
- Capacity: Up to 1,000 m³/h throughput
- Operating Temperature: Up to 800°C for high-temperature applications
- Sizes Available: From 70 mm to 2,500 mm diameter
- ATEX Compliance: Certified for use in explosive dust environments
- Custom Rotor Designs: Optimized for different material types and flow rates
Additionally, easy maintenance and modular construction reduce downtime and operating costs.
Superior Wear Protection: Ultra-Carbide®
In abrasive or high-wear environments, standard valves can degrade quickly. KREISEL offers Ultra-Carbide®, a proprietary coating technology that significantly extends the life of valve internals. This solution ensures long-term precision and reduces maintenance intervals in demanding applications like cement or mineral handling.
