Product Description

Positive Pressure Conveying Drop-through Rotary Valves are the most basic and common type of rotary valve. Usually they are widely used in the powder and granule positive pressure pneumatic conveying systems. They feed material that falls through the inlet, moves down though the rotating vanes where it drops out the bottom outlet flange via gravity. This design is capable of feeding materials in a vast array of applications. In a pneumatic conveying system, a convey adapter or shoe must be installed below the valve to transfer the product into the conveying line where it is blown or sucked downstream.


The drop-through valve is used mainly for relatively free-flowing, non-cohesive materials such as grain, rice, coffee beans, salt, and sugar.
