Proportional hydraulic valve current controller

Controller for proportional hydraulic valves with current regulation, protection logic, external control and device documentation.

Task

What had to be solved

The controller had to regulate current through a proportional hydraulic valve and provide predictable control for an external system or operator.

Result

What the project reached

A compact controller was prepared with operating modes, external control, protection behavior and documentation.

Development and debugging
Thermal check

Project materials

Photos and working materials

Two assembled units

Documentation

Device manual

Engineering context

Important constraints

The output stage works with an inductive hydraulic valve load.

Current regulation and safe behavior during mode switching were important.

The device needed clear external-control and manual-control options.

Work done

What was included

Power-stage and current-measurement circuitry.

Firmware for current regulation and operating modes.

Protection and diagnostics behavior.

PCB design, prototype testing and device manual.
