The Doebritz Vacuum Loader Bottom Discharge Rotary Valve is a highly specialized material handling component that functions as an ultra-reliable rotary airlock. It achieves consistent volumetric feeding and absolute gas sealing specifically designed to maintain the negative pressure of vacuum conveyors and suction loaders in powder systems.
Vacuum conveying systems require strict air-locking at the discharge point; any air leakage drastically reduces the system's suction power. Built to prevent vacuum loss, this specialized rotary valve is widely deployed beneath vacuum receivers, pneumatic loaders, and suction feeders in the pharmaceutical, food, and fine chemical industries.
To guarantee stable operations under continuous industrial vacuum stress, 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 | Up to 634 L/min |
| Sealing Performance | Double Sealing (Air-tight for Vacuum) |
| Structure Design | Easy Cleaning (Quick Wash Type) |
Integrating this Doebritz rotary valve provides immediate, tangible value to your material handling system. It actively eliminates vacuum leaks to restore suction power, drastically improves discharging stability, and significantly lowers maintenance downtime via its highly accessible easy-cleaning design.
Vacuum loaders operate by creating negative pressure to suck powder into a receiver. If the bottom valve leaks, ambient air rushes in, destroying the vacuum and causing the conveying process to fail. Our double sealing technology guarantees air-tight operation.
Absolutely. The tight internal clearances act as a highly reliable airlock specifically suited for both severe vacuum suction (-0.5 bar) and positive pressure pneumatic conveying (up to 2 bar).
Extremely easy. The "Easy Cleaning" mechanism allows operators to safely open the side assembly and wash the rotor directly, preventing cross-contamination without needing to dismantle the pipeline connection to the vacuum receiver.
