When emptying, dust goes via inlet hole into blades of the valve and, after they turned, it is ejected via outlet hole. Emptied cells of rotating drum reach the inlet hole again and take another portion of dust. This cycle repeats regularly till the rotary valve drive is switched off. After stop of the drum the rotary valve plays a role of valve shutting off flow of dust and air. Flow of dust between inlet and outlet takes place without decompression.
Body and blades of the rotary blades are made of cast-iron or steel. For materials, which wipe off the interior, devices can be made of abrasion-proof material
In order to avoid de-compression during operation of the rotary valve, its blades can be additionally equipped with replaceable sealing
As a standard, to drive the rotary valve drum there are used moto-reducer assemblies
