The Doebritz Hygienic Rotary Valve is an advanced material handling equipment explicitly designed for fine, sensitive materials. It serves as a highly reliable airlock, achieving stable feeding and precise pressure isolation within pneumatic conveying systems.

Engineered to meet the most rigorous sanitary standards, this rotary valve is widely utilized in the food industry. Typical application scenarios include food powder processing, milk powder production lines, flour milling facilities, and hygienic dust collection systems.

• Hygienic Design (Ra < 0.8)
  Manufactured from premium stainless steel, all internal surfaces are mirror-polished to a roughness of Ra < 0.8. This prevents fine powders from bridging or sticking, effectively eliminating the risk of cross-contamination.
• Easy Cleaning Structure
  The valve features an easy cleaning structure that allows operators to rapidly access internal components. This is vital for dairy and bakery processing where frequent and thorough sanitation is required.
• Stable Conveying Performance
  The precision-engineered rotor guarantees a uniform and consistent feed rate, preventing material blockages and ensuring stable conveying for highly fluid powders.

• Pressure Integrity
  Operates flawlessly and safely within a system pressure range of -0.5 to 2 bar.
• Thermal Adaptability
  Withstands diverse processing environments with working temperatures ranging from -10 to 150°C.
• High Processing Capacity
  Engineered for industrial-scale production, delivering a maximum capacity of up to 634 L/min.

Integrating the Doebritz hygienic rotary valve into your milk powder or flour production line provides immediate, tangible value. It significantly reduces material leakage, dramatically improves conveying stability, and drastically lowers long-term maintenance and cleaning costs.
