The Doebritz Interchangeable Impeller Extractable Rotary Valve is an exceptionally versatile material handling component. It functions as an ultra-reliable rotary airlock, achieving consistent volumetric feeding and absolute gas sealing within complex powder pneumatic conveying systems, with the unique ability to adapt to different material characteristics.
Designed for multi-product facilities that frequently switch between handling fine powders, cohesive materials, and coarse granules. This specialized rotary valve is widely deployed in:
To guarantee stable operations under aggressive industrial stress and frequent changeovers, our equipment is backed by verified engineering parameters:
| Specification | Details |
|---|---|
| Material | Stainless Steel (SUS304 / SUS316L) |
| Working Pressure | -0.5 to 2 bar |
| Working Temperature | -10 to 150°C |
| Max Capacity | 110-634 L/min |
| Rotor System | Interchangeable (Closed / Open Impeller) |
| Structure Design | Quick Dismounting (Extractable Type) |
Integrating this Doebritz rotary valve provides immediate, tangible value to your processing plant. It actively eliminates material jamming by matching the right impeller to the product, drastically improves conveying stability, and significantly lowers maintenance downtime during product changeovers via its highly accessible extractable design.
A closed impeller prevents fine, free-flowing materials from leaking past the rotor ends, while an open impeller prevents cohesive or sticky materials from packing and jamming. Having both allows your single valve to handle any material flawlessly.
Absolutely. With precise internal clearances, it acts as a highly reliable airlock specifically suited for both vacuum and positive pressure conveying (-0.5 to 2 bar).
It is incredibly straightforward. The "Quick Dismounting" extractable mechanism allows operators to slide the rotor assembly out, swap the impeller, and slide it back in within minutes, requiring no specialized tools or pipeline disassembly.
