EIMA INTERNATIONAL 2022

EPX technology is made of a Flow Sharing directional control valve, an electronic joystick, a Load Sensing pump and an electronic control unit with customizable modular software developed by Walvoil (PHC STUDIO).

EPX technology is based on new compensator's function with a recovery line R powered by flow in pressure (Power).

Once the recovered flow is available in the line R, its management depends on the choices of the equipment manufacturer. It is possible to regenerate the recovered flow into the system directly, to store it in a hydraulic accumulator, or to transform it in electrical energy and store it in a battery.

The EPX system is capable of lowering consumption and returning a share of energy, with overall energy savings of up to 20%, depending on the type of application.

The new Walvoil Tractor Solutions allow you to meet all the requirements of the most sophisticated and modern technologies on the latest generation tractors.
The Walvoil solution introduced at eima includes the new DKP120 sectional valve, the CAN bus NG5 electronic module and the Hitch control valve.
The DPK120 is a pre-compensated sectional valve for open/closed centre circuits, specifically designed for tractors and front loaders. It is equipped with a wide and flexible range of options; it has an input compensator for energy optimization, working sections with "zero-leak" check valves, and is widely configurable with manual proportional controls, hydraulic, electrohydraulic proportional controls, including the new electronic module CAN bus NG5.
This new proportional electrohydraulic control NG5 is also used on the section of the DPK120 dedicated to Hitch Control, replacing the manual adjustment with efficient and precise management of all machine implementations.
The new Hitch Control section managed via CAN bus supports the PWM version already available on the SD8 valve, by expanding the solutions available for the control of agricultural machinery.
