Breakthrough in China domestic technology replacing imported products: Hanrui Puzer successfully developed zero-crush rotary valves for POE conveying！
In the field of pneumatic conveying systems, the handling of Polyolefin Elastomers (POE) presents unique challenges due to the material’s distinctive physical and chemical properties. POE is a highly elastic, low-density polymer with a tendency to stretch, compress, or fragment under mechanical stress. Currently, all domestic pneumatic conveying systems rely on imported rotary valves to transport POE materials. However, extensive market research and customer feedback have exposed significant shortcomings in these imported solutions.
Key Issues with Imported Rotary Valves:
-
High Costs – Imported rotary valves come with substantial procurement expenses, including long lead times, customs duties, and high maintenance costs, which place a heavy financial burden on manufacturers.
-
Material Crushing – The rigid design and high shear forces generated by conventional rotary valves often lead to excessive crushing of POE particles, resulting in inconsistent granule sizes and degraded material performance.
-
Material Drawing and Fragmentation – Due to POE’s elastic nature, the rotating components of standard valves can stretch or tear the material, causing unwanted elongation or breakage that compromises product integrity.
-
Negative Impact on Product Quality – These issues collectively affect the final product’s uniformity, mechanical properties, and processing efficiency, leading to increased waste and production inefficiencies.
Hanrui Puzer’s Breakthrough in Rotary Valve Technology
For over 22 years, Hanrui Puzer has been at the forefront of pneumatic conveying innovation, consistently prioritizing customer needs and tackling industry pain points. Recognizing the limitations of existing rotary valves in POE applications, our R&D team embarked on an intensive research and testing campaign to develop a specialized solution.
Technological Advancements:
-
Zero Material Crushing – Our redesigned rotary valve features a low-shear, gentle conveying mechanism that eliminates excessive compression, ensuring POE granules remain intact throughout the transfer process.
-
Anti-Drawing and Anti-Fragmentation Design – By optimizing rotor geometry, sealing mechanisms, and rotational speed, we have completely eliminated material stretching and fragmentation, preserving POE’s original properties.
-
Precision Engineering for Elastic Materials – The valve incorporates advanced wear-resistant materials and precision-machined components to minimize friction and maintain smooth, consistent material flow.
This breakthrough marks a milestone in domestic technological independence, successfully replacing imported rotary valves with a superior, cost-effective alternative. By adopting Hanrui Puzer’s solution, customers benefit from:
✔ Reduced operational costs – Eliminating reliance on expensive imported equipment.
