Cable-operated hydraulic control valves – precise control in demanding systems
Cable-controlled hydraulic valves are advanced components that enable remote operation of working systems in agricultural, forestry, and construction machinery. Their main task is to distribute the flow of working fluid to specific receivers, while ensuring the operator has full control over the operation of hydraulic cylinders or motors. Thanks to the use of mechanical cable control, the operator can be located at a safe distance from the main hydraulic block, which significantly improves ergonomics and work safety.
Our range includes high-class valves that guarantee smooth operation even under variable loads. If you are looking for solutions dedicated to specific applications, check out our forestry machinery control valves, which are characterized by increased resistance to off-road conditions. For agricultural machinery, where simplicity and reliability are required, we recommend the four-section control valve, allowing for the handling of multiple functions with a single device.
Application and benefits
Cable-operated valves are used wherever mounting the block directly in the cabin or near the operator is technically impossible or unjustified. They are standard in front loaders, cranes, and forklifts. By using cables for control valves of high quality, we ensure precise control without so-called "dead spots" in the lever's operation.
Main benefits of using cable-operated control valves:
- Possibility of installation anywhere on the machine, saving workspace.
- High precision of flow control thanks to the smooth transfer of movement from the lever to the spool.
- Increased operator safety by separating the control station from high-pressure components.
- Ease of service and the possibility of quick cable replacement without having to dismantle the entire block.
- Compatibility with various types of joysticks and levers, allowing for full personalization of the workstation.

Frequently Asked Questions (FAQ)
How to choose the right cable length for the control valve?
The cable length should be selected taking into account the casing's bending radii – radii that are too small cause increased operating resistance. We recommend measuring the path from the joystick to the block with a slight reserve.
Can cable-operated valves be combined into multi-section sets?
Yes, most of our models allow for expansion by adding further working sections, making them modular solutions.
What to do if the cable provides high resistance during operation?
First, check the routing of the casing for kinks. If the cable is not mechanically damaged, the cause may be contamination of the ends – in such a case, it is worth considering replacing the entire element.
