Lever-operated hydraulic control valves – precise control of power systems
Direct lever-operated hydraulic control valves are the foundation of efficient power hydraulic systems, responsible for directing the oil flow to working actuators. These devices allow for manual control over hydraulic cylinders and motors, guaranteeing direct translation of lever movement into the displacement of the spool in the valve block. By eliminating indirect control systems, lever mechanisms ensure immediate system response, which is essential in agricultural, forestry, and construction machinery requiring high work dynamics. Every hydraulic control valve available in our offer meets rigorous tightness and pressure strength standards.
Technical characteristics and installation
The offered valves are made of high-grade nodular cast iron, which guarantees resistance to sudden pressure spikes up to 350 bar. For the system to work reliably, it is necessary to use appropriate fittings. For sealing the connections, we recommend using professional bonded seals, and for the connection to the actuators themselves – durable hydraulic hoses with appropriate flow capacity. In case of system modernization, it may be necessary to use hydraulic connectors and hydraulic reducers, which will allow for quick adaptation of threads without the need for costly modifications.
Proper oil hygiene is crucial for the longevity of the spools. Therefore, alongside hydraulic filters within the system, it is worth ensuring cleanliness while refilling the medium by using filler breathers. In situations where the lever needs to be moved to another location, we offer ready-made control cables, and for service and regeneration – dedicated control valve parts
Why choose our components?

FAQ – service and operation
1. How to check if the control valve needs sealing?
Visible oil leaks under the levers or self-lowering of the cylinder with the lever locked is a signal that it's time to order service parts.
2. Can I replace a lever-operated control valve with a cable-operated one?
Yes, in many cases, it is sufficient to replace the so-called "lever housing" (adapter) with one adapted for cables, which you can find in the category service accessories.
3. What oil should be used in a system with a control valve?
We recommend high-quality hydraulic oils, which ensure optimal spool lubrication and anti-corrosion protection for the entire system.
