  Function
Blow-Through Rotary Valves
Blow-Through Rotary Valves
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.
