The Doebritz Adjustable Clearance Rotary Valve is an advanced material handling component engineered for precision and longevity. It functions as a highly reliable rotary airlock, achieving consistent volumetric feeding and absolute gas sealing within demanding powder pneumatic conveying systems.
Application Scenarios
Standard valves suffer from increased air leakage due to rotor wear over time, or material jamming due to thermal expansion. Built to overcome these critical issues, this specialized rotary valve is widely deployed in abrasive powder processing, high-temperature chemical conveying, pharmaceutical processing, and sanitary food ingredient handling.
Core Advantages
Adjustable End-Face Clearance (Stable Conveying): Over time, handling abrasive powders wears down rotor blades, causing pressure loss. Furthermore, temperature variations can cause metal expansion, leading to jamming. Our innovative external adjustment mechanism allows operators to easily fine-tune the rotor end-face clearance without dismantling the equipment. This restores perfect sealing, prevents jamming, and guarantees exceptionally Stable Conveying.
Easy Cleaning: Frequent batch changes require rapid washdowns. The intuitive quick-access structure allows operators to swiftly open the housing to thoroughly clean the interior. This minimizes downtime and prevents cross-contamination.
Stainless Steel Build: Manufactured entirely from premium Stainless Steel (SUS304 / SUS316L), the internal surfaces resist chemical corrosion and structural wear, ensuring a prolonged operational lifespan.
Performance Data
To guarantee stable operations under continuous industrial stress, our equipment is backed by verified engineering parameters:
Pressure Resistance: Safely maintains perfect sealing performance in pneumatic lines operating under pressures from -0.5 to 2 bar.
Thermal Adaptability: Functions securely across a wide working temperature range of -10 to 150 °C, with the adjustable clearance compensating for thermal expansion.
Processing Capacity: Engineered for industrial-scale efficiency, delivering highly accurate volumetric throughput with a maximum capacity of up to 634 L/min.

Key Benefits
Integrating this Doebritz rotary valve provides immediate, tangible value to your processing plant. It actively eliminates air leakage and extends equipment lifespan through its adjustable clearance feature, drastically improves conveying stability, and significantly lowers maintenance downtime via its easy-cleaning design.
Frequently Asked Questions
Why is an adjustable clearance better than a fixed clearance?
A fixed clearance will inevitably widen due to abrasive wear, causing air leakage. An adjustable clearance allows you to continuously tighten the gap back to factory specifications, extending the valve's lifespan and maintaining optimal airlock efficiency.
Does it support pneumatic conveying systems?
Absolutely. By maintaining tight internal clearances, it acts as a highly reliable airlock specifically suited for both vacuum and positive pressure conveying (-0.5 to 2 bar).
How is the rotary valve cleaned?
Maintenance is highly efficient. The "Easy Cleaning" mechanism allows operators to safely open the assembly to wash away residual powders and resume operations rapidly.
