Efficient dosing processes: Control vs. regulation - what makes the difference?
In industrial dosing processes, controlling the quantity dispensed is crucial for quality and efficiency. But how can you ensure that dosing is always precise? We compare four different control models and show how the Walther Valve Controller (WVC) drastically reduces the integration effort. Figure 1 (🇬🇧 5): Classic PLC control without feedback
The valve is opened for a fixed time ⏱️, but the actual quantity discharged can fluctuate - e.g. due to changes in pressure or viscosity. Without measuring the actual discharge quantity, process reliability remains limited.Figure 2 (🇬🇧 6): PLC with volume flow meter for process evaluation (IO/NIO)
Measuring the discharged quantity is possible, but involves a high level of integration effort (additional hardware, software adaptations, calibration and fine adjustment). Figure 3 (🇬🇧 7): WVC control with volume flow meter for process evaluation (IO/NIO)
Low integration effort via plug-and-play: Automatic calibration and compensation of dead times facilitate commissioning. The volumetric flow is controlled directly via the WVC, without complex PLC adaptations.Figure 4 (🇬🇧 8): WVC as a control system
The highest level of process control: regulation instead of control! The WVC dynamically adjusts the valve opening time to ensure a constant discharge rate - regardless of external influencing factors such as pressure or viscosity fluctuations. Conclusion: If you want process reliability with minimum effort, there is no way around a solution with the WVC!

Cured and ready for operation
The spray valves of the WSV series are designed for use in industrial production environments with increased mechanical, thermal and environmental loads. For this reason, Walther Systemtechnik deliberately relies on protective methods such as potting of electronic components during the manufacture of the valve assemblies. The potting process reliably protects the integrated electronics against mechanical impact, moisture, contamination, as well as extreme temperatures and thermal cycling, thereby making a significant contribution to long-term functional reliability. The valve heads shown here have been potted with a high-quality two-component polyurethane resin. After curing, the resin increases the mechanical stability of the assembly and ensures reliable operation of the spray valves even under demanding industrial conditions.

Lubrication of rolling bearings – project successfully completed
For the precise lubrication of rolling bearings, Walther Systemtechnik has developed and successfully implemented an advanced lubricant application system. The system specifically addresses the high requirements for component lubrication in rolling bearing production, particularly for small batch sizes and a high degree of product variation.
The core of the solution is the use of pulse valves, which enable pinpoint and reproducible lubricant application. The system is designed to be adapted quickly and efficiently to changing production requirements. Automation, low set-up effort, integrated recipe management and continuous process monitoring are consistently combined within a single solution.
High flexibility and fast changeover: By simply replacing the gripper jaws, the system can be quickly adapted to different bearing dimensions and bearing types. This enables short set-up times and economical production even with frequent product changeovers.
Automated lubrication process: Manual loading of the rolling bearings is complemented by a fully automated sequence. This includes component pick-up, positioning and alignment, single- or double-sided lubricant application, and subsequent component removal. The result is consistently high quality and excellent repeatability of the lubrication process.
Integrated recipe management: Lubricant recipes and application parameters can be stored and retrieved on a bearing-type-specific basis. This increases process reliability, reduces operating errors and ensures that each bearing variant is lubricated exactly in accordance with its technical requirements.
Reliable process control: Integrated monitoring functions continuously safeguard the lubricant application process. Dispensed volume and application position are monitored, ensuring precise dosing and a high level of process stability.

Walther WPV Pulse Valve: An innovative evolution in process technology
Pulse valves enable contactless dispensing of viscous media with a high level of repeatability. By dispensing individual droplets in rapid succession, even very small quantities can be applied at high frequencies while maintaining consistent precision. This makes pulse valves particularly suitable for applications with high cycle rates, as typically found in series production and automated processes. Even difficult-to-access or uneven component geometries can be handled reliably. Conventional pulse valve systems, however, are often associated with a high level of integration effort. External control technology, complex programming and additional software increase both investment and commissioning costs and at the same time raise the potential for errors. Against this background, the Walther WPV pulse valve was developed to combine the functional advantages of pulse dispensing with significantly reduced system complexity. Functional integration instead of external control: the WPV pulse valve is characterised by a high degree of functional integration within a compact design. Control, monitoring and process evaluation are integrated directly into the valve. No additional external control system, dedicated software or programming effort is required. Operation consistently follows the principle of “parameterising instead of programming” – from commissioning through to ongoing process monitoring. Access to the valve’s own dashboard is provided via a web interface. Functions such as remote parameterisation and remote diagnostics enable flexible adjustment of process parameters as well as rapid analysis of process conditions. In addition, peripheral components can be controlled and evaluated without the need for a higher-level control system. Equipment and operating concept: the standard equipment of the WPV includes an integrated pressure sensor, a valve heating system with temperature control, as well as analogue and digital inputs and outputs for connecting external components. Fully electric operation eliminates the need for compressed air lines, reduces installation effort and space requirements, and lowers operating costs. By combining contactless dispensing with integrated control and monitoring technology, the WPV opens up new possibilities for efficient, highly automated dispensing processes while at the same time reducing overall system complexity. Process control and expandability: multiple parameter sets can be stored and process-relevant variables documented. This has a positive effect on process capability, overall equipment effectiveness (OEE) and product quality. In addition, software add-ons can be activated retrospectively as required to flexibly address future requirements.

World Savings Day – and what it has to do with dispensing technology
Saving is not only a matter of cost, but above all of efficiency. Those who deploy resources in a targeted and controlled manner increase productivity while simultaneously reducing material and process costs. For this reason, integrated process monitoring plays a central role in the development of new products at Walther Systemtechnik. Whether pump systems, valve control units or smart application valves, integrated monitoring functions create transparency regarding the current process status. Using pressure monitoring with the Walther ValveController WVC as an example, it becomes clear how relevant process parameters can be continuously recorded and evaluated. Users thus gain a reliable real-time overview of their fluid application process. Systematic process monitoring makes it possible to detect quality deviations at an early stage and correct them in a targeted manner. This reduces scrap and rework, directly contributing to cost savings. In addition, further benefits arise: Early detection of process faults to avoid unplanned downtime and increase system availability Process optimisation through more efficient use of media, energy and resources Data-driven decision-making that supports continuous improvement of process stability and quality Process monitoring is therefore a key element in increasing quality, efficiency and productivity in industrial manufacturing. At the same time, it helps to sustainably reduce costs and strengthen the long-term competitiveness of companies.

A simple trick for challenging containers
As part of a recent project, we encountered a particular challenge: a subsequent delivery arrived in a container with a special design feature. Similar to a paint tin, the upper rim was fitted with an encircling collar that narrowed the opening. This made it more difficult to insert the follower plate of our conveying system into the container.In principle, the medium could be transferred into a suitable standard container in such cases. However, a far more efficient solution is to adapt the container itself. By cleanly cutting off the lid, the collar can be removed and the container can continue to be used without issue. A smooth, burr-free cutting edge is essential to ensure reliable operation of the follower plate.A surprisingly simple tool proves highly effective here: a standard household tin opener allows the lid to be cut evenly and cleanly along the rim. This enables the container to be prepared quickly and without additional tools for use in the conveying system.A small, practical tip that saves time and simplifies material handling when dealing with non-standard containers.

Efficient drum emptying for greases and lubricants
For the reliable conveying of greases and highly viscous lubricants directly from the drum, Walther Systemtechnik offers high-performance pumping systems for process-reliable emptying of OEM containers. In addition to proven standard solutions, application-specific customised versions are also available, precisely tailored to the respective process requirements. One example is the integration of an air bubble elimination unit. With many viscous media, the reliable detection and removal of air inclusions is critical, as these can impair downstream components and negatively affect dispensing processes. The integrated air bubble elimination protects the overall system and ensures that subsequent processes run in a stable, reproducible and precise manner. Advantages of the integrated air bubble elimination: Continuous monitoring of the medium for air inclusions Automatic discharge of the affected portion of the medium Minimal media loss, as only the contaminated portion is removed Uninterrupted media release, even during venting and drum changeover In addition, the system enables the acquisition of production-relevant process parameters. This contributes to increased process capability and improved overall equipment effectiveness (OEE). If you would like to learn more about the conveying of viscous media, drum emptying systems or customised solutions, please feel free to contact us.
