The petrochemical industry involves the transportation and processing of a large amount of granular materials, often accompanied by complex working conditions such as high temperature, high pressure, high corrosiveness, and easy agglomeration

 In the power industry — especially coal-fired, biomass, and waste-to-energy plants — large volumes of high-temperature dust, fly ash, and slag are generated and must be discharged efficiently. Rotary valves play a crucial role in dust collector systems and ash handling, and must endure abrasion, heat, and high operating cycles over time. 

Rotary valves are widely used in environmental protection systems as key components for dust collector discharge, positive and negative pressure pneumatic conveying, and sealed dust unloading. In common systems such as baghouse dust collectors, cartridge filters, and cyclone separators, rotary valves must offer excellent air tightness, stable discharge capacity, anti-blocking performance, and a compact structure to ensure continuous, safe, and compliant operation throughout the dust removal process. 

 In the food industry, the conveying and discharging of powder materials require not only precision and stability, but also strict compliance with hygiene, safety, and cleanability standards. Common materials such as flour, milk powder, additives, flavorings, and leavening agents are typically fine, hygroscopic, and prone to cross-contamination, placing high demands on the rotary valve’s sealing performance, residue control, and easy-to-clean design. 

 Powder handling in the pharmaceutical industry places extremely high demands on equipment, particularly in terms of cleanliness, control precision, structural sealing, and ease of cleaning to meet application requirements. Common materials such as pharmaceutical powders, granules, intermediates, and excipients must be conveyed and discharged in a sealed, dust-free, and contamination-free environment with accurate dosing. 

 In the metallurgical industry, powder conveying and discharging processes often involve complex working conditions such as high temperatures, severe abrasion, large particles, and heavy-duty continuous operation. Common materials like iron oxide powder, mineral powder, pellet feed, metallurgical waste, and lime powder impose stringent requirements on the rotary valve’s strength, wear resistance, air tightness, and structural stability.
