Scheuch COMPONENTS rotary valves – for dosing, feeding and discharging
Used in industrial processes, rotary valves principally perform the tasks of dosing, feeding and discharging granulates and products with a dust-like or fine-grained structure. They provide a safe, efficient and gentle way of handling powders and granulates at a range of different levels. Rotary valves are equally at home in the food industry, chemical companies, plastics production and the minerals industry.
In light of the requirements regarding safety and explosion protection, which represent an ever increasing challenge, our rotary valves are EC type-examined in accordance with Directive 2014/34/EU. They meet category requirements CAT 1, CAT 2 and CAT 3 and are therefore suitable for use in Zone 20, Zone 21 and Zone 22.
Furthermore, our rotary valves have been tested and certified in line with “protective system” requirements. Explosion testing with regard to ignition source safety and flame arresting devices was carried out by notified bodies with European certification.

What does a rotary valve do?
A rotary valve can take on lots of different jobs, depending on what is required of it, but its main task is to discharge dosed quantities of bulk material that can then move on to further treatment stages.
Rotary valves that are installed under silos and other repositories reduce the pressure that the bulk materials exert on the immediately adjacent components in a transport chain. Their dosing-based method of discharging also takes the strain off trough screw conveyors and other systems, including scales. Not only that, but rotary valves even provide burn back protection in cases where they are used with combustible materials.
What types of rotary valve are available?
Rotary valves come in a variety of designs to suit all kinds of different tasks. Please get in touch if you need any information about the specific features that our products contain – whether you need a small rotary valve or something suitable for handling large volumes, Scheuch COMPONENTS has a solution to suit your requirements.

Which kinds of rotary valve are best for which tasks?
The rotary valve you choose will depend on what exactly you need it to do. We’d be delighted to help you find the perfect solution for your application – and whatever you need a rotary valve for, we can deliver it in a range of different sizes to create the perfect match for the speed of your conveying systems.
How long does it take to clean a rotary valve during a batch change?
More and more, today’s businesses need to offer flexibility and accommodate a variety of products. That’s why we’ve designed our rotary valves to make sure they can be cleaned in no time at all – so production can get up and running again quickly after a batch or bulk material has been changed. Every component that requires cleaning is easy to access and quick to deal with, significantly reducing the time spent on cleaning and boosting productivity.
