rotary air conveying Dec


Rotary valves - types, applications, and specifications.

Rotary valves (also known as rotary airlocks, rotary feeders, etc.) are pneumatic valves that handle and meter the flow of granular bulk or powders. Material is fed into the valve via a hopper (see Figure 1) or other inlets, handled through the valve rotor, and then deposited onto a conveyor system in discrete packets, all with minimal pressure ...

Side Entry Rotary Airlock Valves | Carolina Conveying ...

Side-Entry Rotary Airlock Valves. The Side Entry Rotary Airlock Valve is used in applications where product shearing is a concern. The valve name derives from the offset inlet and outlet flanges, where the product enters the side of the rotor instead of the top. On a normal valve, shearing takes place as the rotor rotates into the housing.
