Hydraulic control valves 80 l/min with quick couplers
Hydraulic control valves with a nominal flow of 80 l/min are the main control units dedicated to managing the flow of the working medium in power hydraulic systems of agricultural, forestry, and construction machinery. These devices provide precise control of single-acting and double-acting cylinders, guaranteeing stable operation even under maximum load. Factory integration of the control valve block with quick couplers allows for instant connection of working equipment without the need for external adapters, significantly reducing technical downtime. The design ensures high performance in demanding environmental conditions, eliminating energy losses in the system.
Application and technical characteristics
The offered control valves are designed to work in circuits supplied with mineral oils, synthetic oils, and water-oil emulsions meeting the viscosity requirements for hydraulic systems. These devices are used in installations with pump capacities up to 80 l/min, where maintaining constant speed parameters of the actuators is required. The slider control mechanism is based on precise direct levers, allowing for stroke repeatability while maintaining a stable working pressure of up to 250 bar. The control valve bodies are made of ductile iron, which increases their resistance to material fatigue caused by dynamic pressure spikes. The internal precision of the slider manufacturing minimizes internal leaks, preventing load drop in the neutral position. The quick coupler set is designed in the ISO standard, ensuring full compatibility with most hydraulic hoses used in mobile machinery. During the system service process, dedicated hydraulic control valve parts, which allow for maintaining the full efficiency of the device throughout its service life. To ensure the cleanliness of the medium inside the system, we recommend regular inspection and replacement of elements in the hydraulic filter system.
Why choose our components?
The choice of our control valve blocks is based on technical reliability and high operational efficiency. The use of integrated quick couplers limits the number of potential leak points, which is the most important environmental protection in modern machinery parks. To eliminate the negative impact of system vibrations on the pipeline, we recommend using our pipe and hose clamps, which stabilize the rigid elements of the installation. Each working section has been manufactured with care to minimize pressure drops, which directly increases the energy efficiency of the entire hydraulic system. Our solutions are ready-made components that are immediately prepared to work under full load after installation.

Frequently Asked Questions (FAQ)
- Does the control valve with quick coupler type connections require additional thread seals?
- No, the quick couplers offered in the set have integrated high-resistance seals that guarantee the tightness of the connection without using additional washers.
- What are the causes of a noticeable drop in cylinder speed at a flow of 80 l/min?
- The drop in speed may result from a clogged filter element, excessively high oil viscosity at low temperatures, or incorrect setting of the relief valve inside the section.
- Can the control valve be integrated with a joystick control system?
- Yes, the block design allows for the replacement of manual levers with adapters for Bowden cables or direct joystick control, which increases working ergonomics.
- Are the quick couplers in this model replaceable in case of mechanical damage?
- Yes, the quick couplers are mounted in the body using standard hydraulic threads, allowing for their quick replacement without the need to dismantle the entire control valve.
