The Doebritz Hygienic Rotary Valve is a high-precision airlock feeder designed for pharmaceutical environments. It is specifically engineered to achieve stable feeding and reliable pressure isolation within pneumatic conveying systems, ensuring the integrity of your powder processing lines.

This professional-grade valve is essential for industries with stringent hygiene requirements. Typical application scenarios include pharmaceutical powder processing, sterile API handling, sensitive chemical powders, and high-end cleanroom systems.

Our valve is defined by three critical selling points that establish market trust:

• Hygienic (Ra < 0.8)
  All internal contact surfaces are mirror-polished to Ra < 0.8, effectively preventing material buildup and ensuring a sterile environment compliant with cGMP standards.
• Easy Cleaning & Quick Dismounting
  The innovative structure allows for rapid, tool-free disassembly. This facilitates thorough cleaning and validation, significantly reducing production downtime during batch changes.
• Stainless Steel Construction
  Manufactured from high-grade SUS316L or SUS304 stainless steel, providing superior corrosion resistance and long-term durability in pharmaceutical environments.

We use hard data to demonstrate the equipment's stability and reliability:

• Pressure Integrity: Operates securely within a working pressure range of -0.5 to 2 bar, maintaining a perfect airlock.
• Thermal Resilience: Withstands a broad temperature spectrum from -10 to 150 °C, adapting to various pharmaceutical processing conditions.
• Processing Capacity: Capable of high-efficiency material handling with a maximum capacity of 634 L/min.

Integrating the Doebritz hygienic rotary valve solves several critical production issues:

• Reduces Contamination Risk: The mirror-polished hygienic surfaces ensure no residue remains.
• Improves Conveying Stability: Maintains uniform feed rates even under varying pressure conditions.
• Lowers Maintenance Costs: The quick-dismounting design allows for faster cleaning cycles and reduced labor.
