Abrasion-Resistant Rotary Valve

November 11, 2014

FLSmidth’s abrasion-resistant rotary valve helps to maximize the performance and dependability of a pneumatic conveying system by combining several essential features in a single unit. The rotary valve’s ceramic lining and tungsten carbide coatings provide a long operating life with minimal maintenance requirements. It reduces downtime and maintenance costs, and has three to four times longer life compared to other designs.
 
The excellent abrasion resistance is due to a .1-in.-thick ceramic bore and .1-in.-thick tungsten carbide rotor vane and shroud tips, and tungsten carbide throat protection.  
 
The heavy-duty rotary valve can handle abrasive materials in both pressure and vacuum pneumatic conveying systems. The valve can feed material at up to 9.1 cu ft per revolution, handle differential pressures up to 15 psi, and operate in temperatures up to 350°F.
