This is how transportation of tomorrow looks like
coax® valves in Talgo's first fuel cell train

Hydrogen as one of the energy sources of the future is used for decarbonization in a variety of industries. It already plays a major role in the transport industry. coax® customer Talgo sets the hydrogen application in rail transport in motion.

Hydrogen propulsion offers an emission-free alternative for non-electrified railway lines. For this purpose, the hydrogen is obtained from renewable energies. Due to its low volume-related energy density, it is compressed and stored under high pressure. After that, the gaseous hydrogen is fed to the fuel cell-based system, which supplies the subsequent electric motor with electricity.

The customer of our Spanish subsidiary co-ax válvulas, s.l and provider of products and services in rail transport "Talgo" is currently building its first prototype for fuel cell trains.

For this prototype customized müller coax valves control the hydrogen supply from the hydrogen tank to the fuel cell.

The customer was particularly impressed by the extremely high level of tightness of the coax® valves to the outside and on the valve seat. To ensure this, the valves are subjected to a vacuum test at coax before delivery. With decades of experience in the hydrogen sector, we are ready for the challenges of today and tomorrow.
