Control Devices
Browse control devices for hydraulic systems, construction machinery and industrial equipment. These components help manage electro-hydraulic functions, machine operation and precise control of hydraulic valves and actuators.
Find the correct control device by OEM number, manufacturer reference, control function, voltage, connector and machine application.
Control Devices for Hydraulic and Electro-Hydraulic Systems
Hydraulic control devices are electrical, electronic or electro-hydraulic components used to manage machine functions and hydraulic system operation.
They can be used to control valves, pumps, motors and actuators in construction machinery, industrial equipment and mobile hydraulic systems.
What Do Hydraulic Control Devices Do?
Depending on the design, a control device may:
- send commands to hydraulic valves,
- regulate proportional valve operation,
- control hydraulic pump output,
- manage motor speed or direction,
- receive signals from switches and sensors,
- coordinate multiple machine functions.
Electro-Hydraulic Control
Modern machinery increasingly uses electro-hydraulic control systems. These systems combine hydraulic power with electrical or electronic signals to achieve more precise machine operation.
Examples include proportional valve control, electronic pump regulation and automated hydraulic sequences.
How to Select the Correct Control Device
Important identification data includes:
- OEM number,
- manufacturer and model,
- control function,
- operating voltage,
- connector and pin configuration,
- input and output signal type,
- machine manufacturer and model,
- compatibility with the hydraulic component being controlled.
OEM Number and Software Compatibility
For electronic control devices, matching the physical connector may not be sufficient. Depending on the machine, the control device may require specific calibration, programming or software compatibility.
Voltage and Signals
The electrical supply and signal type must match the machine control system. Incorrect voltage or incompatible signals can prevent operation or damage electronic components.
Common Symptoms of Control Device Problems
- hydraulic function not responding,
- intermittent machine operation,
- incorrect proportional control,
- machine diagnostic fault codes,
- communication errors,
- unexpected valve or actuator behaviour.
Before replacing a control device, inspect wiring, power supply, ground connections, sensors, coils and the hydraulic components connected to the control system.

FAQ – Hydraulic Control Devices
What is an electro-hydraulic control device?
It is a component that uses electrical or electronic signals to control hydraulic functions.
Can a control device be replaced only by matching the connector?
No. Voltage, signals, software, calibration and machine compatibility may also need to match.
Why does a hydraulic function work intermittently?
Possible causes include damaged wiring, connectors, coils, switches, control devices or hydraulic components.
What information is needed to identify a control device?
OEM number, manufacturer reference, voltage, connector, machine model and control function are the most useful data.
