History & About Us

Our main products currently include limit switch boxes, solenoid valves, mounting parts and mounting kits. Our customers can procure all products related to pneumatic actuators -and nowadays also linear actuators- from a single source. For limit switch boxes alone, we offer 7 different series fulfilling a wide range of requirements. Solenoid valves are available in NAMUR and in-line versions and we offer mounting kits for manually operated valves, linear actuators and between actuators and valves. These products are essential for the automation of industrial processes and are used in various industries, including the chemical, oil and gas, water and wastewater industries. Our limit switch boxes are particularly renowned for their reliability and durability, as are our solenoid valves, which also impress with their precision and efficiency. The mounting parts and mounting kits offer flexible solutions for integrating our products into existing systems.
We want to sleep soundly and therefore attach great importance to a high standard of quality, which is reflected in the extremely low number of complaints. For example, our limit switch boxes are subjected to a 100% function test before they leave our premises. Although we operate in a niche market, we are one of the leading suppliers on the global market. By continuously innovating and adapting to the needs of our customers, we have built up a strong market presence.
However, it is not only quality that is important, but above all good customer service. In our eyes, this includes
- prompt preparation of quotations
- short delivery times
- transparent and comprehensive product documentation
- open and honest consulting
- expertise
- a cooperative partnership with the customer
- and, most importantly, swift assistance if a problem arises
Key milestones
Partner companies abroad:
Since the beginning of the company's history, we have always had partner companies abroad, such as in Holland, Malaysia, Australia, Italy and China.
We have always brought new products onto the market, where not only the function was important to us, but also an appealing and modern design. Some of our innovative products have revolutionised the market and are now indispensable.
Reversible seal for MNF
For example, we launched the innovative reversible seal for our solenoid valves, which switches the function of a solenoid valve from 5/2 to 3/2-way by simply removing, turning and reinserting it. This makes stock-keeping easier since our customers need only one solenoid valve for double-acting and single-acting actuators. The principle has already been copied several times.
Adjustable bracket MBH
We were also pioneers in the market for mounting brackets between the actuators and limit switch box, launching a height and width-adjustable version. Previously, there was a separate, one-piece bracket for each standard bore pattern. With our MBH bracket, we combine a total of 8 different bore patterns and shaft heights in one product by simply adjusting the sides. This has also significantly simplified stock-keeping for us and our customers. It is now an absolute market standard and many competitors have now followed suit with similar solutions.
Assembly kit for manually operated valves
Position feedback from valves with manual levers is also frequently required. Especially in safety-relevant applications. We have launched a standardised ‘MSH’ mounting kit to put an end to tedious tinkering in customer workshops. We have also introduced a height-adjustable version to the market, which can be quickly and easily mounted directly on a large number of valves using a variety of driver screws. With this set, both limit switch boxes and double sensors can be installed and we have been able to win over all well-known sensor manufacturers as customers.
Products through the years










Certifications
DIN ISO 9001
This standard has helped us to grow in a healthy way through structured processes and at the same time has laid the foundation for further certifications.
ISO IEC 80079-34
As a certified manufacturer for ATEX and IECEx products, we have been able to capture new markets for ourselves. Today, we generate a whopping 40% of our turnover with products for the explosion-protected area. All other certificates that we require for other countries are based on this certification.
Processes/Machinery
One-piece flow
The changeover from island production to the one-piece flow system was certainly a major milestone in production. We also paid attention to ergonomics and built all assembly tables to be electrically height-adjustable. This form of line production has reduced the throughput times of our large orders to a minimum and set the first important milestone towards partial automation.
Robot technology
In 2022, we also acquired a robot, which we are currently learning a lot with and which can already perform simple work steps independently.
3D printing
3D printing is a fascinating manufacturing technique that has made us super flexible in our reorganisation of production. In the beginning, we only used it to produce aids and brackets for our assembly tables, but today we already have a total of three of these printers and also produce parts for our products in small batches.
