Valves for aviation – technology for extreme conditions

Challenges in the aviation industry

In aviation, designers, purchasers, and system integrators face unique challenges. It is not just a matter of controlling liquids or gases—it is also about safe operation at high altitudes, with pressure fluctuations, and under extreme climatic conditions. Areas of application such as cabin air conditioning, hydraulics, fuel systems, and CO₂ cooling pose requirements that go far beyond those of traditional industries:

Vibrations, pressure surges, and temperature changes must not impair functionality.
Every seal and every weld must be documented and traceable.
Space and weight are critical – every gram counts
Maintenance and replacement must be quick and easy.

In short: Standard valves often fail here—what is needed are solutions that think for themselves.

Our solution for the aviation industry

We offer modular valves that are specially designed for use in aircraft technology. Depending on the application, we combine media-separated plastic valves with compact coaxial valves or electrically controlled control valves—always adapted to your system architecture.
The following have proven particularly successful:

Coaxial valves with external control unit: For precise control in cabin and cooling processes
Valves with nickel-plated or stainless steel reinforced housings: For aggressive media or high pressure ranges
Servo-controlled control valves: For sensitive pressure and flow control under changing conditions
Aviation-certified plastic valves with PVDF or PTFE components: For hygienically sensitive systems

Our modular system reduces development time, enables customization, and delivers exactly what is needed—no more, but also no less.

Advantages of our aviation valves at a glance

Temperature resistant – from frosty altitudes to hot engine proximity
Corrosion-resistant – resistant to kerosene, coolants, hydraulic oils
Extremely durable – designed for millions of switching cycles without maintenance
Compact and lightweight – ideal for confined spaces and weight restrictions
Full documentation – material certificates, test reports, serial numbers
Modularly scalable – single unit or series, special solution or standard design

Project examples from aviation

cabin pressure control with coaxial valves An aerospace supplier needed a compact valve to control cabin air flows. Our solution: a servo-controlled coaxial valve with feedback—space-saving, vibration-resistant, and easy to install.
CO₂ cooling circuit in onboard climate control systems
We supplied nickel-plated plastic valves with media-separating diaphragms for use in a CO₂-based climate control system. The result: reliable switching performance even with highly fluctuating outside temperatures and high differential pressure.
Valve block for fuel control in the engine environment
Metal valves with reinforced seals and specific pressure control, adapted to the harsh environment near the engine – including complete CE and material documentation. FE seals precisely control the urea input in the SCR system – durable despite aggressive media.

Why our aviation valves work

We don't rely on standardization—we rely on structure. Our valve construction kit allows familiar functional units to be adapted to new requirements. No tedious redesign, just a clever combination of proven modules—tailored to your needs.
Instead of individual components, we build scalable systems:

For air conditioning systems
For hydraulic and fuel lines
For media routing in hygiene-critical areas
For pressure and flow control in flight systems

Result: shorter project durations, consistent quality, and predictable costs.

FAQ – Valve technology in the aviation industry

From kerosene and CO₂ to hydraulic oil or compressed air—we precisely match the housing material and seal to the application medium. This makes our systems versatile—from supply to control.

Yes. Our valves operate from cryogenic altitudes to over 150°C near the engine—without any loss of performance.

Of course. PVDF and PTFE-based plastic valves with media-separating diaphragms are particularly suitable for CO₂ cooling systems, drinking water, or sensitive gases.

Thanks to our modular design and our warehouse, many projects can be implemented within a few days—from configuration to prototype.

We provide material certificates, ISO certificates, CE conformity, and, upon request, complete serial number documentation—prepared for audits and project approvals.

Our designs are conceived in such a way that they can be easily integrated into existing control or hydraulic systems – both mechanically and electronically.
