The Doebritz Double Sealing Rotary Valve (Star Valve) is a highly engineered material handling equipment tailored for ultra-fine bulk materials. It functions as a robust rotary airlock, achieving consistent feeding and absolute gas sealing within demanding dense phase pneumatic conveying systems.
Fine mineral powders like talcum and calcium carbonate are notorious for being highly penetrative and prone to packing. Built to survive these harsh conditions under high pressure, our specialized rotary valve is widely deployed in mineral processing lines, chemical powder handling, plastics compounding, and heavy-duty dust collection systems.
To guarantee stable and reliable operations under aggressive industrial stress, our equipment operates flawlessly within 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 |
| Power Supply | Customized based on specific bulk density loads |
| Structure Design | Easy Cleaning / Double Sealing Design |
Integrating this Doebritz rotary valve provides immediate, tangible value to your processing plant. It actively reduces material leakage of fine mineral powders, dramatically improves conveying stability across your high-pressure dense phase line, and significantly lowers maintenance costs and equipment replacement frequency through its accessible, well-protected design.
A: Yes, the heavy-duty stainless steel construction combined with our specialized double sealing technology makes it highly resistant to internal leakage and bearing damage caused by ultra-fine, penetrative powders.
A: Absolutely. With precise internal clearances and excellent pressure isolation capabilities, it acts as a highly reliable airlock specifically suited for the high-pressure demands (-0.5 to 2 bar) of dense phase conveying.
A: Maintenance is straightforward and efficient. The "Easy Cleaning" mechanism allows operators to rapidly access the internal housing to inspect rotor clearances, wash away caked powder, and resume operations with minimal downtime.
