Electrically controlled hydraulic directional control valves – advanced system automation
Modern power hydraulics require precision, response speed, and the ability to easily integrate with control systems. Electrically controlled hydraulic directional control valves form the foundation of modern construction, agricultural machinery, and industrial lines. The use of solenoid valves allows for remote management of the working medium flow direction without the need for complex mechanical systems. Our offer includes solutions that allow for full process automation, which significantly increases the operational efficiency of devices.
Every directional control valve available in our range is characterized by high internal tightness and resistance to difficult working conditions, including temperature fluctuations and high operating pressures. Thanks to the use of high-quality components, such as reliable coils for hydraulic solenoid valves, our solutions guarantee long-term operation in the most demanding environments. The offered directional control valves work with a wide range of supply voltages, which facilitates their implementation in mobile and stationary installations.
Application and principle of operation
The principle of operation of electrically controlled directional control valves is based on the use of electromagnets which move the control spool via magnetic force. This solution eliminates energy losses associated with manual operation and allows for precise control via PLC controllers, microprocessors, or simple desktop switches. In more extensive systems, where the operator needs smooth control over the actuator movement speed, it is worth considering supplementing the system with proportionally controlled directional control valves or sections with variable characteristics.
The use of these components is indispensable wherever cycle repeatability is required. They are used in hydraulic presses, front loaders, lifting platforms, or central lubrication systems. In case of needing to modify an existing system, our store also offers the necessary parts for hydraulic directional control valves, which allow for quick regeneration or adaptation of the device to new technical parameters.
Benefits of implementing electric control
- High switching dynamics: Short reaction time of the solenoid valve increases the efficiency of the executive device.
- Process precision: Remote control capability allows for better control over the machine in real-time.
- Work ergonomics: Elimination of manual levers improves operator comfort and allows the control panel to be placed in an optimal location.
- Safety: Easy implementation of "fail-safe" protections – in the event of power failure, the valve can automatically return to the neutral position.
- Ease of maintenance: Modular design allows for replacement of individual components, which reduces operating costs in the long term.

FAQ – Frequently Asked Questions
What voltage should I choose for my directional control valve?
Voltage selection depends on the machine's electrical installation. In vehicles and mobile machines, 12V or 24V DC is standard. In stationary industrial systems, 230V AC is usually used.
Why did the directional control valve stop responding to the electric signal?
The most common cause is a burnt solenoid coil or a problem with the current supply (wires, plugs). You should also check if the spool inside the valve has not become blocked due to contaminants in the oil.
Can electric control be combined with manual control?
Yes, versions of directional control valves equipped with so-called manual override (emergency) are available, which allow manual operation of the machine in the absence of electricity.
