Electrohydraulic operation

Hydraulic pilot spool with coil Proportional electrohydraulic control is usually generated by a controller or electronic actuator.

The controller or electronic actuator regulates the current supplied to the valve’s solenoid coil based on a reference signal from an input device.

The current produces a magnetic field that moves the dcs-sis.com armature, which in turn moves the hydraulic spool or spool of the pilot section, or in some cases acts directly on the spool.

The coils all have resistance, which usually varies with temperature. For good electro-hydraulic control, it is necessary to be able to regulate the current to accommodate temperature/resistance variations.

In addition, manufacturing and design differences in coils and hydraulic valves can cause performance to vary from valve to valve, even if they are of the same type.

Optimal electro-hydraulic control requires the ability to manage and adjust all parameters that may affect coil current and valve flow or pressure.

Parker ECD offers a wide range of controllers and displays to build state-of-the-art electrohydraulic control systems.

Electrohydraulic (EH) control is the effective proportional control of hydraulics through the use of solenoid coils.
