- Remotely Controlled and Explosion-Proof: Pneumatic actuation allows use in sensitive, explosion-prone environments – a key advantage in hydrogen systems.
- Versatile and Media-Resistant: Suitable for gaseous, liquid, and even contaminated media – robust against typical challenges in hydrogen operations.
- Compact, Durable, and Low-Maintenance: Space-saving design, long service life, and reliable performance even under demanding conditions.
- Energy-Efficient with Fast Switching: Low control air consumption and short switching times ensure precise and cost-effective process control.
coaxial Externally Controlled Valves VMK
Efficient Coaxial Design
The valve features a coaxial construction, allowing the media to flow straight through the housing. This minimizes pressure loss and ensures a consistent, stable flow – especially important for the safe and controlled handling of hydrogen.
Remotely Actuated Function – Ideal for Safety-Critical Applications
Pneumatic actuation enables use in areas where electrical components must be avoided, such as explosion-prone hydrogen systems. This makes the valve particularly suitable for safety-relevant applications in hydrogen technology.
High Media Compatibility and Flexibility
The VMK 10 is designed for a wide range of media – including gases, liquids, and even contaminated or abrasive substances. This makes it an excellent fit for various process steps in hydrogen systems, from production and storage to distribution.
Compact and Robust Design
Thanks to its space-saving construction, the valve can be easily integrated into confined system layouts. At the same time, high-quality workmanship ensures long service life, even under frequent switching and demanding operating conditions such as high pressures or aggressive media.
Energy Efficiency and Fast Response Times
Low control air consumption makes the valve especially energy-efficient – a key factor for sustainable hydrogen applications. Short switching times also enable precise control and fast response in process operations.

müller co-ax gmbh
coax® – Valve Technology that Drives the Hydrogen Future
müller co-ax gmbh delivers cutting-edge valve solutions for every stage of the hydrogen value chain – from production to application:
- Hydrogen production / electrolysis
- Storage
- Transport
- Refueling
- Test benches
Our coax® valves are specifically engineered for hydrogen-based systems. They combine a compact design, high flow rates, wide pressure ranges, and the use of hydrogen-resistant materials – making them ideal for installation in tight or space-constrained environments.
With integrated limit switches, valve positions (open/closed) can be directly and reliably detected – a critical feature for automated systems and safety-relevant applications.
A standout feature: The magnetically operated coax® valves are uniquely designed to remain leak-tight to the atmosphere even if the seals begin to wear. In other words, there is no operational connection to the external environment – ensuring zero hazardous leakage, no skin contact with media, and maximum operational safety.
These closed valve assemblies are the perfect choice for demanding media such as gaseous hydrogen, liquid ammonia, or methanol – and are ideally suited for use in explosive environments.
