In coal handling plants, rotary valves are vital for managing the flow of abrasive coal dust and ash while maintaining a strict pressure seal. Built to withstand extreme wear, these valves prevent air leakage in pneumatic systems and ensure the safe, controlled discharge of fuel into boilers. Using heavy-duty materials like Ni-hard or Hardox liners, Pyramid’s rotary valves are engineered to resist high temperatures and abrasion, significantly reducing maintenance costs and preventing system clogs in demanding power plant environments.
