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.
