coaxial pneumatically operated valves FCF 25 -150
- High flow & low pressure drop – The axial flow minimises pressure losses and enables efficient hydrogen delivery.
- Safe & durable design – Robust materials and precise manufacturing ensure high tightness and a long service life, essential for hydrogen systems.
- Fast & reliable switching times – The low-friction mechanism ensures fast switching, which is ideal for dynamic hydrogen processes.
- Flexible installation & wide range of applications – Suitable for various hydrogen applications with variable installation positions and connection options.
- High pressure resistance – Designed for pressures up to 40 bar, ideal for hydrogen systems in industry and mobility.
coaxial poppet valves FCF 25 -150
- High flow & low pressure drop
- The special axial flow design of the FCF valves ensures that hydrogen is transported with minimal resistance. This is particularly important because hydrogen, being the lightest element, has a high diffusion capacity and pressure losses in pipelines and valves must be kept to a minimum in order to maximise system efficiency.
- Safe & durable design
- Hydrogen requires extremely tight and material-safe components, as it can diffuse through conventional materials (hydrogen embrittlement). FCF valves are made of high-quality, hydrogen-resistant materials that prevent corrosion and embrittlement. Their durable design ensures a high level of operational reliability and reduces maintenance – crucial for applications in H2 filling stations, pipelines or industrial hydrogen processes.
- Fast & reliable switching times
- In dynamic hydrogen applications, such as refuelling processes or fuel cell systems, precise control of the gas flow is essential. The low-friction mechanism of the FCF valves enables fast switching, minimising delays in the process chain. This leads to increased efficiency and process reliability.
- Flexible installation & versatile application options
- The valves can be installed in any position, making them flexible for various hydrogen applications – be it in research facilities, mobile hydrogen storage tanks or industrial production plants. They are also available with different connections (e.g. flange PN 16/40) to fit optimally into existing H₂ infrastructures.
- High pressure resistance & resilience
- Hydrogen is often stored and transported at high pressures. FCF valves are designed for operating pressures of up to 40 bar, making them suitable for high-pressure applications in the hydrogen economy. They are also designed for up to 50 switching cycles per minute, which makes them ideal for frequent operating cycles, for example in filling stations or automated hydrogen systems.

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.
