ALS – Adaptive Electro-hydraulic System for the Efficiency of Mobile Machines

Walvoil ALS - Adaptive Load Sensing System, presented at EIMA 2024 in its advanced version, addresses the need for more advanced controllers that minimize energy consumption without sacrificing operator experience.

Thanks to ALS, it is possible to change the “pressure margin” of the system: the control signal for the pump or input compensator is modulated to meet different operational needs.

ALS is a synergistic set of components for the efficiency of mobile machines.

The joint control of the hydraulic directional control valve and the pump makes it possible to cut down pressure drops due to the pressure margins of the metering system.

In addition, a range of logics are available to improve machine control, productivity and driving comfort.

The ALS System, part of the Hydraulic Digital Solutions, enables a reduction in fuel consumption of more than 5-6%, and can be used as an integral part of the hydraulic directional control valve or inserted on the variable displacement pump.

Walvoil offers three different ALS solutions to provide extreme versatility and adapt to the performance and system requirements of the machine.
