The Doebritz side-extractable stainless steel rotary valve (star discharge valve) is an advanced material handling equipment designed to act as a highly reliable airlock, achieving stable feeding and completely preventing material jamming within complex pneumatic conveying systems.

Built to handle difficult and sticky materials with superior reliability, this rotary valve thrives across multiple demanding sectors including chemical powder handling, food powder processing, heavy-duty dust collection systems, and grain transport.

• Quick Dismounting (Side-Extractable)
  Traditional valves cause prolonged downtime during blockages. Our innovative side-extractable structure allows operators to effortlessly pull the internal rotor out from the side for deep cleaning and immediate inspection without dismantling the main pipeline.
• Stable Conveying (Anti-Jamming)
  Precision-machined rotor pockets and optimal internal clearances prevent material bridging. The anti-jamming design ensures an exceptionally uniform and stable conveying process regardless of load fluctuations.
• Stainless Steel Construction
  Constructed from high-grade stainless steel (SUS304 / SUS316L), it offers outstanding durability, eliminates rust risks, and complies with strict industrial sanitation protocols.

To guarantee stable and reliable operations under complex conditions, our rotary valves are backed by rigorous, verified technical data:

• Pressure Resistance
  Safely maintains perfect sealing integrity in systems operating from -0.5 to 2 bar.
• Thermal Adaptability
  Operates flawlessly across a wide working temperature range of -10 to 150 °C.
• High Processing Capacity
  Delivers exceptional quantitative throughput for continuous operations with a maximum capacity of up to 634 L/min.

Integrating this Doebritz rotary valve provides immediate, tangible value to your material handling line. It actively reduces material leakage, dramatically improves conveying stability by eliminating jams, and significantly lowers maintenance costs through its accessible side-extractable design.
