RVS Blow-Through Rotary Valves

Supplier: Chain & Drives

RVS Blow-Through Rotary Valves consist of a tubular cast iron or stainless steel casing, a horizontally mounted rotor with a certain number of oblique V-shaped cross section compartments, a drive unit and a casing cover at each end.

Price Guide: POA


Two compartments at a time of the continuously turning rotor are filled up with material through the inlet at the top of the Rotary Valve.

After less than half a turn the material falls through the bottom opening into an air stream passing through a pneumatic conveying pipeline connected with the bottom part of the Rotary Valve.
