   Rotary Airlock Valve

Rotary Airlock Applications Rotary Valve Models  
Rotary airlocks are important components of pneumatic conveying, bulk solids handling and batching  systems. Rotary airlock is also known as rotary valve, rotary feeder or airlock feeder. The main function of a rotary valve is to control flow of bulk solids from silo, mixer, cyclone or hopper under gravity, pressure and vacuum conditions. Airlocks can work on pressure and vacuum applications.

Rotary Valve Applications

Silo emptying, cyclone discharging, dust collection systems, dosing, batching, mixing, pneumatic conveying applications, conveyor feeding / unloading, screw feeder feeding / discharging, machinery and equipment feeding / discharging

Airlock for silo discharge



Rotary Valve Models:

There exists large number of airlock models for different applicaitons and bulk solids. Silo, cyclone, jet filter, conveyor, pneumatic transpostation applications need different type of  airlock valves. The type of the bulk solid (temperature, moisture, dimensions, abbrassion, hardness, elasticity etc) also important for selecting correct airlock model.
