Stainless Steel Hygienic Rotary Valve with Quick Dismounting for Stable Conveying in Food Processing

The Doebritz Clamp Connection Hygienic Rotary Valve is a top-tier sanitary material handling component designed as an ultra-reliable, contamination-free rotary airlock. It achieves consistent volumetric feeding and absolute gas sealing within stringent food and pharmaceutical pneumatic conveying systems.

Built to eliminate all sanitary dead zones where traditional bolted flanges create microscopic crevices for bacterial growth, this specialized rotary valve is widely deployed in:

• Dairy powder processing
• Infant formula manufacturing
• Pharmaceutical active ingredient handling
• Sanitary conveying systems requiring frequent, rigorous washdowns

Replacing traditional bolted flanges with universal Tri-Clamp connections ensures a completely smooth, crevice-free transition between pipeline and valve. All surfaces are polished to strict hygienic standards (Ra < 0.8), preventing bacterial growth and material residue.

Frequent batch changes demand rapid cleaning. The innovative slide rail structure allows operators to swiftly pull the internal rotor assembly out without tools, enabling complete unit opening, washing, and inspection in minutes.

Precision-machined internal clearances strictly control air leakage while preventing shearing of sensitive food granules, guaranteeing exceptionally uniform and stable conveying under continuous production.

Verified engineering parameters ensure stable operations under strict sanitary protocols and CIP/SIP cleaning processes:

• Pressure Resistance: Maintains perfect sealing performance from -0.5 to 2 bar
• Thermal Adaptability: Functions securely across -10 to 150°C, resisting thermal deformation during sterilization
• Processing Capacity: Delivers highly accurate volumetric throughput up to 634 L/min

Integrating this Doebritz hygienic rotary valve provides immediate, tangible value to your food-grade processing plant by:

• Eliminating bacterial contamination risks through sanitary clamp design
• Drastically improving conveying stability
• Significantly lowering maintenance downtime via tool-free slide rail extraction

Clamp (Tri-Clamp) connections provide a seamless, crevice-free joint that is completely smooth on the inside, preventing powder accumulation. They allow rapid valve disconnection without wrenches or bolt removal.

Absolutely. Despite the quick-release clamp design, it acts as a highly reliable airlock specifically suited for both vacuum and positive pressure conveying (-0.5 to 2 bar).

Maintenance is tool-free and highly efficient. The "Quick Dismounting" slide rail mechanism allows operators to unclamp the side housing and smoothly pull the rotor out to wash away food residues, meeting strict FDA and GMP cleaning requirements.
