The Doebritz Stainless Steel Quick Dismounting Rotary Valve is a premium material handling component available through our full-service OEM custom manufacturing program. It functions as an ultra-reliable rotary airlock and precise volumetric feeder, explicitly engineered to deliver consistent material flow and absolute gas isolation within demanding powder pneumatic conveying systems.
Application Scenarios
System integrators, engineering firms, and machinery brands require versatile, high-precision airlocks that conform exactly to their unique system drawings and hygienic codes. Built to serve diverse global standards, our customizable quick-opening rotary valve is widely deployed beneath storage silos, cyclone collectors, dosing hoppers, and mixing stations in the food processing, pharmaceutical, fine chemical, and battery powder industries.
Core Advantages
Quick Dismounting (Fast Washdown Design): Modern powder handling requires rapid batch changeovers to eliminate cross-contamination. Our innovative quick-opening mechanism allows technicians to unlatch the front end-plate and extract the rotor assembly within minutes without using tools. This enables immediate visual inspection and thorough cleaning, dramatically cutting maintenance downtime.
Stable Conveying: Precision CNC machining achieves extremely tight internal clearances between the stainless steel rotor blades and housing. This maintains a rugged pressure seal, eliminates blow-back gas leakage, and guarantees perfectly stable conveying.
Stainless Steel Execution: Manufactured entirely from heavy-duty stainless steel (SUS304 / SUS316L), the interior surfaces prevent product discoloration, resist corrosive chemicals, and strictly comply with international sanitary processing codes.
Flexible OEM Manufacturing: We provide full white-label and OEM solutions—including tailored flange patterns, custom drive mountings, specialized surface polishes (Ra < 0.8 μm), and private label logo laser etching.
Performance Data
To guarantee stable performance under continuous industrial stress and pressure differentials, our OEM-manufactured 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: Resists thermal deformation and functions securely across a wide working temperature range of -10 to 150 °C.
Processing Capacity: Engineered for industrial-scale throughput, delivering controlled volumetric output with a maximum capacity of up to 634 L/min.

Frequently Asked Questions
Q: What custom modifications can Doebritz provide under the OEM program?
A: We offer extensive customization, including bespoke flange dimensions (ANSI, DIN, JIS), specialized rotor pocket shapes (V-shaped anti-shear or closed-end), custom surface finishes (mirror polish or bead blast), motor brand selections, and custom logo etching.
Q: Does the quick dismounting design compromise the airtight pressure seal?
A: Not at all. When the quick-opening end cover is locked into position using our industrial clamping system, it compresses heavy-duty gaskets to form a gas-tight structural seal that safely maintains precise pressure containment between -0.5 and 2 bar.
Q: How fast can operators remove the rotor for cleaning during batch switchovers?
A: It takes only a few minutes. The tool-less quick dismounting mechanism allows a single operator to release the fast-clamps, pull out the rotor assembly, thoroughly wash or wipe the internal chamber, and lock it back into place without removing the main valve body from the pipeline.
