Pressure regulation unit

Our customized, modular valve is specially developed for regulating the pressure of hydrogen in fuel cells and hydrogen combustion engines. It offers a reliable solution for the safe and efficient control of the hydrogen flow and can be flexibly adapted to different requirements.

Modular pressure regulation unit for pressurized hydrogen

With the experience gained from the first generation of 700 bar stainless steel valves, VOSS is positioning itself as a pioneer in the hydrogen sector.

The new, modular valve family has been specially developed for applications in the commercial vehicle sector that require high flow rates (Hydrogen Commercial Flowrate). The valves offer customized solutions for the efficient regulation of pressure and can be flexibly configured to be optimally adapted to different needs.
