customized rotary valve


For ensuring continous control or regulated function, rotary valves are preferred in many processes like food and chemical processing, pharmaceutical and plastics manufacturing, dosage control, mixing, batching and many others like silo discharging, pneumatic conveying line feeding and discharging.

Rotary valves can be used with almost every material in powder or granular form of bulk solid and can be solution for various application areas and industries such as food, cement, iron, steel, agriculture, chemicals and plastics. However, each process is unique and should be handled well. Not only rotary valves are used for ensuring minimum loss of air pressure at the beginning or end of pneumatic conveying lines, but also they are used for providing volumetric and gravimetric feeding for continuous mixing and streaming solutions.

Handled materials can be one of the bulk solid materials from cement, fly ash, mining minerals, calcium carbonate, pvc, plastic pellets, plastic powders, polyethylene, ceramic powders, alumina, bentonite, bauxite, coal, cement clinker, gypsium, perlite, kaolin, limestone, marble powder, soda ash, quartz, urea, sodium sulphate, wheat, flour, animal feed, seed, corn, rice, sugar and salt.

Each successful  application is a result of good observation of the material to be handled and experience on difficulties and challenges of that specific process. Some applications might require large diameters, unique inlet-outlet flanges, heavy duty housing, non-standart dimensions, reduced rotor volume, special flange connections,  non-standard body designs and special accessories or some customers might ask for replacement of a discontinued brand / model or total cast iron or steel construction models.

Custom engineered production incorporates problem definition, conceptualization, design, validation, production and installation. Polimak engineers carry out these steps efficiently and provide custom engineered solutions in very short times.
