The operation of a conveyor belt consists of the continuous movement of a belt mounted on platforms with variable dimensions and which may have different types of accessories (side guards, stops, diverters, railings, wheels, and other types of pneumatic or mechanical accessories). Speed and load capacity will depend both on the characteristics of the material to be conveyed (dust, fine grain, packages, etc.) and the type of conveyor belt.

Operation using a Y to which two valves are mounted to select the desired path by opening one valve and closing the other. It is comprised of a Y-shaped pipe and 2 sleeve or ball valves.

There are different formats of diverter valves. These may be constructed in-house or commercially available; the latter may use rotary drums to eliminate the valves. Measurements vary according to the pipe to be used and if they are treated. They may be coated internally with anti-wear materials to minimise abrasion.

In direct flow rotary valves, the bulk solids drop into the inlet of the rotor chambers. The rotation of the rotor displaces the material downwards and is blown horizontally through the connection of the conveying pipe (in vacuum and discharge). Its special design allows the circulating air through the conveying pipe to completely clean the rotor.

Materials:

Manufactured in carbon steel, stainless steel, aluminium, Ni-hard. Possibility of chrome, tungsten, or nickel-plated interior coatings, and multiple rotor constructions.

Dimensions:

There are different sizes from DN50 to DN 500, with flow rates adapted to each need. We offer direct flow rotary valves for conveying pipes from DN-65 to DN-200.

Outward airtightness:

Airtightness with the outside is achieved by the use of seals (NBR or PTFE), with or without back pressure, depending on the use of the rotary valve. Lid pressurisation system may be included.

Drive:

Depending on the valve model, it may also be activated by a gear motor directly attached to the rotor and supported on the side cover of the valve. This type of gear motor provides high power density and can handle large radial loads.
