The Doebritz Cyclone Bottom Discharge Rotary Valve is a highly engineered material handling component that functions as an ultra-reliable rotary airlock. It achieves consistent volumetric feeding and absolute gas sealing specifically designed for the bottom discharge of cyclone separators in powder pneumatic conveying systems.
Cyclone separators require strict air-locking at the discharge point to function correctly. Built to prevent upward air bypass, this specialized rotary valve is widely deployed under:
Commonly used in food, chemical, and mineral processing industries.
Any air leaking upward through the bottom valve disrupts the cyclone's vortex, drastically reducing powder separation efficiency. Our precision-machined rotor and advanced Double Sealing system create a perfect airlock, strictly preventing air bypass and ensuring your cyclone operates at peak performance.
Powders collected by cyclones can often build up or require frequent batch changes. The intuitive quick-access structure allows operators to rapidly open the side housing to thoroughly wash and inspect the interior without unbolting the heavy valve from the cyclone cone.
Manufactured entirely from premium stainless steel (SUS304 / SUS316L), the structural integrity resists abrasive powder wear and chemical corrosion, ensuring a prolonged operational lifespan even in continuous discharging applications.
Pressure Resistance: Safely maintains perfect sealing performance in pneumatic lines operating under pressures from -0.5 to 2 bar.
Thermal Adaptability: Resists thermal deformation and functions securely across a wide working temperature range of -10 to 150 °C.
Processing Capacity: Engineered for industrial-scale efficiency, delivering highly accurate volumetric throughput with a maximum capacity of up to 634 L/min.

Integrating this Doebritz rotary valve provides immediate, tangible value to your processing plant. It actively:
A cyclone relies on a stable downward vortex to separate powder from air. If air leaks upward through the bottom discharge valve, it disrupts this vortex, causing valuable powder to be sucked back into the exhaust stream. Our double sealing design prevents this completely.
Absolutely. The tight internal clearances act as a highly reliable airlock specifically suited for both vacuum dust collection and positive pressure conveying (-0.5 to 2 bar).
Maintenance is highly efficient. The "Easy Cleaning" mechanism allows operators to safely and rapidly open the side assembly to wash away residual powders without having to detach the valve from the cyclone bottom.
