When there is no margin for error in the system, every detail counts. Our valves for vacuum technology are designed with this in mind.
Valves Vacuum technology – Tight solutions for demanding processes
Challenges in vacuum technology
Vacuum technology begins where classic plant engineering standards reach their limits. As soon as air pressure is reduced or even completely removed, the rules change. Materials behave differently, leaks become a hazard, and every connection, every seal, and every control must be designed for maximum tightness.
The challenges that our vacuum technology customers describe to us often sound similar:
- "How can I prevent leakage when the negative pressure changes?"
- "Which valves work reliably in high vacuum processes?"
- "How can I achieve a long-lasting seal without constant maintenance?"
- Are there modular valve solutions that can handle aggressive media in a vacuum?
This requires solutions that come not from a catalog, but from practical experience.
Our solution for valves in vacuum technology
We develop and supply valve technology that is specially designed for use in vacuum environments. Whether plastic valves for sensitive media, metal valves for high-vacuum applications, or coaxial valves with reduced dead space geometry—we combine a compact design with adaptable functionality.
Our valves for vacuum technology are used in analytical devices, pharmaceutical equipment, laser systems, process chambers, and coating systems. Depending on requirements, we supply valves with gas-tight seals, media-separated designs, extremely short switching times, or minimal control air consumption.
Advantages of our valves for vacuum technology
- Low-leakage design: permanently sealed housing connections, even under extreme negative pressure
- Media separation for aggressive substances: sophisticated internal geometries and high-quality sealing materials
- Long-term stability: consistent performance even with frequent switching or changing load profiles
- Flexibly configurable: modular design for easy integration into existing systems
- Space-saving and powerful: ideal for compact assemblies or complex vacuum systems
- Suitable for special applications: including temperature resistance, ATEX requirements, or special materials
Examples of valve applications in vacuum technology
- Analysis and research: Use of PVDF-based plastic valves in gas analysis systems with high-precision dosing in the vacuum range.
- Laser technology: Coaxial valves with reduced internal volume regulate the control of carrier gases in laser chambers under controlled vacuum conditions.
- Pharmaceutical process chambers: Control valves made of 1.4571 stainless steel with PTFE seals regulate pressure build-up and release in sensitive applications.
- Semiconductor manufacturing: High-vacuum-compatible metal valves with media-separated diaphragms for controlling process gases in plasma systems.
- Coating technology: Servo-controlled valves for precise vacuum control during sputtering processes with high switching frequency.
Why our valves for vacuum technology work
Vacuum is not a condition in which you can "seal a little." Either it fits—or it becomes expensive. That's why we rely on experience, testability, and uncompromising manufacturing for our valve solutions.
Our products are developed in close collaboration with engineers and users who know exactly which details make the difference in vacuum technology. Whether it's dead space reduction, minimal friction, or material compatibility with aggressive gases, we deliver solutions that make the difference when the system cannot tolerate any errors.

FAQ – Valves for vacuum technology
Our valves are specially designed for tightness and material stability in the vacuum range. Their construction, sealing, and control are optimized for vacuum conditions.
Typical media are nitrogen, helium, oxygen, hydrogen, reactive gases, and special solvents or cleaning media, depending on the sealing material.
Every valve undergoes a leak test. We offer optional leak certificates, test reports, and individually documented series inspections.
Yes. We also supply valves for high and fine vacuum processes—including adaptation of connection geometries, materials, and control units.
For applications with explosive atmospheres, we offer ATEX-compliant coaxial valves as well as variants with external control and encapsulated actuators.
Standard solutions are usually available from stock at short notice. We can usually produce special variants and customizations within a few days thanks to our modular system.
