Rotary Valves for Pneumatic Conveying Systems

As a Critical Component in Dense Phase & Dilute Phase Conveying

Our Rotary Valves, also known as rotary feeders or airlocks, are engineered to be the heart of your positive pressure pneumatic conveying systems. They serve the dual critical function of reliably feeding bulk powder and granular materials into the pressurized conveying line while effectively sealing against air leakage to maintain system efficiency and performance.

Core Functions & Applications

• Primary Function: To discharge material from a hopper or silo into a positive pressure conveying line, acting as an airlock to prevent compressed air from escaping upstream.

• Ideal For: Dense phase and dilute phase pneumatic conveying systems across various industries.

• Key Industries:

  • Lithium Battery New Energy: Precisely handle anode/cathode materials, conductive powders.

  • Fine Chemicals: Pigments, resins, plastic compounds.

  • Pharmaceuticals: Active Pharmaceutical Ingredients (APIs), excipients.

  • Food & Additives: Flour, sugar, starch, food-grade additives.

Key Features & Engineering Advantages

1. Superior Air Seal Technology:

   • Features precision-machined clearances and advanced end plate sealing mechanisms to minimize air leakage. This ensures higher system efficiency, reduces the load on your air compressor, and directly lowers energy consumption.

2. Enhanced Durability & Wear Resistance:

   • Constructed with heavy-duty materials to withstand abrasive materials. We offer customized solutions including high-chrome iron rotors, tungsten carbide coatings, and replaceable wear liners to dramatically extend service life in the most demanding applications.

3. Precision Engineering for Reliable Feeding:

   • The rotor design ensures consistent, uninterrupted material flow, preventing bridging or flushing. This leads to stable and accurate feed rates, which is crucial for downstream process efficiency and product quality.

4. Robust Construction & Low Maintenance:

   • Built with high-integrity housings and premium bearings to ensure reliable, 24/7 operation. Easy-access design simplifies routine inspection and maintenance, reducing downtime and total cost of ownership.

5. Smart-Ready Design (Optional):

   • Prepared for integration with modern Industry 4.0 systems. Options include speed sensors, temperature monitoring ports, and vibration sensors to enable predictive maintenance and seamless integration into your smart factory.

Technical Specifications & Customization

• Sizes: Available in a wide range of standard sizes, with inlet and outlet configurations to fit your existing setup.

• Materials: Carbon steel, Stainless Steel (304, 316L), and other specialty alloys to meet hygiene, corrosion, or contamination requirements.

• Rotor Types: Open, closed, shrouded, or brush-tip rotors to match material characteristics (e.g., fragile, abrasive, cohesive).

• Customization: As a specialist in custom non-standard equipment, we can engineer valves to your exact specifications, including special coatings, sealing arrangements, and dimensional adaptations.
