The transition to sustainable energy sources for mobile machines stems from this global drive to Net Zero.

Digitalisation enables OEMs to optimise their machine design and performance given the limitations of battery capacity compared to the energy content of diesel fuel.

VA mobile valves are the next generation valve series with lower pressure losses than traditional load sense valves thus saving energy.


Vegetable Oil (HVO100) can be blended with diesel to reduce emissions without modifying the machine in any way. On the other hand, Li-ion batteries enable a complete transition from fossil fuels with almost zero emissions. However, Li-ion  machine and require regular recharging.
