Pneumatic conveying rotary valve

powderATEX

Rotary valves are key components in pneumatic conveying systems and in the handling of powdery and granular solids. They are particularly suitable for pneumatic pressure conveying, as they are leak-proof components. Their versatility makes them essential for dosing and material flow control in industrial applications. Air-Tec System has a wide range of specialised suppliers that enable it to offer tailor-made solutions for specific products, such as ‘anti-particle’ systems for granules, rotor coatings for special powders, compartmentalising valves in the case of ATEX-regulated materials, and accessories such as custom-designed loading hoppers and product inlets. CONSTRUCTION MATERIALS Rotary valves can be made from a variety of materials depending on the requirements of the application. Common materials include stainless steel, aluminium, cast iron, and ceramic materials. The choice of material will depend on the nature of the material being transported and the environmental conditions. Closed rotary valves: These valves have small pockets inside the body that collect material during the conveying process and discharge it intermittently. They are ideal for dosing abrasive materials while avoiding possible contact with joints. Open rotary valves: This configuration is the most common used for dosing products, ensuring separation between two environments at different pressures.
