The modern mobile machinery market demands a constant increase in productivity and performance, together with lower operating costs, greater efficiency and reduced emissions in favour of sustainability and social responsibility.
Hydraulic systems have evolved to maximize the predictability of actuation speed. Flow compensation is a well-known technology that mechanically corrects the actuator speed if it exceeds the operator’s demand due to inertial load. This is achieved through a mechanical device introducing a pressure drop to limit the flow when necessary.
EPX concept innovates beyond the industry standard with a three-way device that not only limits actuation speed but also recovers stored gravitational and kinetic energy.

• Synergistic set of components for the recovery of hydraulic energy
• Traditional Flow Sharing architecture
• Energy recovery options based on OEM’s choice
• Prolonged autonomy and reduced battery capacity on electrified machines.
Testing activities on wheel loaders have demonstrated a 20% of energy saving combining recoverable energy and reduction of compensation losses.
