Volkmann diverter valves connect one vacuum conveyor to a number of material loading stations or other systems. By this, a single vacuum conveyor picks up different or the same materials e.g. from silos, big-bags, bag dump stations or from drums through a suction lance.
Volkmann supplies standard diverter valves with 2 to 8 ports as well as customized systems.
Our in-house pneumatic and PLC control engineering experts take care, that all requirements and specific demands are fulfilled. If later on the application is modified, changes can be done easily. The controls are built in-house and are based on different PLC’s manufacturer parts like Siemens, Allan Bradley etc. For the exchange of signals and data, Interfaces to Profibus, CANbus, Ethernet etc. can be included.
A “full” CIP solution is available, too. During rinsing, cleaning and drying the filter remains inside the vacuum conveying system. These come with specific spraying and washing nozzles with rinsing/spray outlet in different directions, have no pocket areas and unique sanitary drain valves for the filter and separator.
The wide range of cleaning options have been successfully transferred to other units like our bag emptying stations.
Furthermore, today Volkmann WIP Vacuum Conveyors are used inside clean-rooms and inside OEB 4 (Occupational Exposure Band 4, OEL 1-10 µg/m³) classified areas.
Special coatings (e.g. Halar®) are used with corrosive materials and conveying environments to protect all parts of the vacuum conveyor.
If the vacuum conveyor itself is installed inside an aggressive atmosphere or comes in contact with aggressive media, the outside of the conveyor will be coated, too. Additionally, MULTIJECTOR Vacuum Pumps are available in various materials (various stainless steel and/or plastic materials) and can be supplied acid-proof.
Certain industries have very strict material requirements, e.g. all equipment must be completely free of copper. As Volkmann manufactures most of its systems in-house, products and solutions with alternative materials can be supplied quite easily.
