Digitalisation in the field of dosing technology: Walther goes digital
23 Sept 2021, 10:00:00
Germersheim, 23 September 2021: The reliable conveying, dosing and application of liquid and pasty media plays a central role in ensuring the function and safety of products in almost all industries. Walther Systemtechnik GmbH has been developing dosing components and systems for over two decades and has established itself as a reliable partner for the realisation of standard solutions through to individual complete systems.
As a driver of innovation, Walther's current I4.0 product family is the latest step in the digitalisation of dosing technology, thus ensuring the future viability of its customers' applications. Whether pumps, media reservoirs, filter systems or modules for air bubble ejection, within the new product family important process and status variables can be recorded in real time using suitable sensors and transferred via analogue and digital interfaces - for example to the system control. This provides the user with new opportunities to increase process capability, Overall Equipment Effectiveness (OEE) and product quality.
This is illustrated by the latest addition to the I4.0 product family, the WSV spray valve. Designed from the ground up for the application of low to medium viscosity fluids, the valve's integrated design provides a high level of functionality in a small footprint. It combines a pressure sensor, a valve heater with associated temperature control and the electronics for controlling, monitoring and analysing process data. An analogue output, four digital inputs/outputs and an Ethernet connection allow extensive connectivity to peripheral devices as well as remote parameterisation and diagnostics of the valve. In addition, software ADD-ONS and firmware updates can be installed and activated at a later date if required, giving the operator maximum flexibility.
Thanks to its compact design, the smart valve can be easily integrated into both new and existing systems. No external control technology or additional programming is required, significantly reducing the cost and time of commissioning.
The greatest added value can be achieved by combining it with other fluid components from the I4.0 product family. Various process data can be evaluated and the resulting process understanding can be used to maximise the system performance indicator.

The Walther Pulse Valve WPV: Innovative evolution of process technology ...
Precise dosing without component contact: Pulse valves represent an excellent solution for dosing a variety of viscous media. Through the repetitive and accurate dispensing of drops, very small quantities can be discharged at high speeds without compromising precision. Therefore, pulse valves are particularly suitable for applications that require high speeds, such as in mass production. In this context, even hard-to-reach and uneven component geometries are rarely a problem. However, the need for a usually complex control and programming presents significant disadvantages, such as associated high acquisition and commissioning costs, as well as an increased potential for errors. To minimize the costly complexity and make this type of media application even more efficient and user-friendly, we have developed the Walther Pulse Valve WPV.
Technological sophistication and integration: The WPV pulse valve is characterized by an optimized design that not only allows for a very small footprint but also incorporates advanced technologies for control, monitoring, and process evaluation. This enables a cost- and time-saving system integration without additional control technology, software, or programming. The motto "parameterize instead of program" extends from commissioning to process monitoring, offering additional possibilities to control and evaluate additional peripheral elements without overarching control.
Access to the valve's own dashboard is easily done via a web interface, providing extensive new options with remote parameterization and diagnosis. Additionally, multiple parameter sets can be stored, and process variables documented. Software add-ons also offer flexibility for future challenges. Other features include a pressure sensor, a valve heating system with temperature control, as well as analog and digital connections for comprehensive connectivity. Remarkably, the fully electric operation eliminates the need for compressed air lines, further reducing integration effort and space requirements while lowering operating costs.
Overall, the WPV impresses with well-thought-out functions and offers a high level of process control, positively impacting process capability, overall equipment effectiveness (OEE), and product quality. Thus, the WPV pulse valve represents a groundbreaking development in dosing technology: the combination of contactless material application and innovative features opens up new possibilities for efficient, highly automated production processes.

Simple trick for difficult containers
The issue has been resolved.Recently, we faced a minor problem when we received a new product delivery. One of the containers had a unique feature - a collar at the upper edge that tapered the opening, similar to a paint can. This presented a small yet significant challenge as it made inserting the follower plate of our conveyor system into the container more difficult.In such a scenario, transferring the contents into a standard container would be a suitable solution. However, a more efficient approach is to cut open the top of the container. It is crucial to ensure a smooth and burr-free separation of the material. This can be achieved easily with the help of a common household item found in nearly every home - a can opener. If you ever find yourself in a similar situation, keep this handy trick in mind!
