Rotary Disc Valves

 

Special construction with rotating disc for highly abrasive products like fly ash and carbon.

Principle: by activating the valve, the valve plate rotates a certain amount which results in continuous grinding. A spring force pushes the valve plate against the seat and compensates for extreme temperature fluctuations. The metallic sealing surfaces are in contact with each other in both the closed and open state, whereby the medium is prevented from entering. Deposits on the sealing surface are cut off by the sharp edge of the valve plate, always keeping them clean.
