Hydraulic directional control valves up to 80L 

The category includes manually operated hydraulic directional control valves ( hand ) lever with a flow rate above 80 liters per minute.  We offer only new valves designed for use in high-pressure hydraulic systems in all types of industries ( agriculture, industry, construction and others ) Our valves are used in construction machinery ( excavators, sweepers, HDS cranes ) agricultural machines ( tractors, log splitters, front-end loaders, cyclops loaders ) and all types of industrial machines using hydraulic oil as a power source. A large valve is a guarantee that the hydraulic oil will not overheat during operation! It is worth remembering this when purchasing. It is worth considering and, for certainty, using a larger 80-liter valve instead of a 40L one. We also offer all types of fittings, connectors, washers and hydraulic hoses for connecting the valve. In case of any questions, please contact the sales department. 

Hydraulic directional control valves with a larger flow rate 

Hydraulic directional control valves with a flow rate up to 80 liters per minute are components in hydraulic systems, enabling precise control of the direction of hydraulic oil flow to individual recipients, such as cylinders or hydraulic motors. This makes it possible to effectively control movement and force in agricultural, construction and industrial machinery. Hydraulic directional control valves adapted for a flow up to 80 l/min are characterized by: High performance: They enable efficient operation of the hydraulic system while maintaining appropriate response speed. Variety of configurations: They are available in versions from 1 to several sections, allowing for the control of many recipients simultaneously. Solid construction: Made of materials resistant to high pressure and intensive operation, which ensures long service life and reliability.

Choosing the right flow - why it is so important 

Impact of too low oil flow in the valve. Insufficient oil flow in a hydraulic directional control valve can lead to several undesirable effects: System performance drop: Limited flow results in slower operation of cylinders or other actuators, which can reduce machine work efficiency. Oil overheating: Too low flow can cause increased flow resistance, which leads to excessive heating of the hydraulic oil. Overheated oil loses its lubricating properties, which can lead to accelerated wear of system components. Operating instability: Insufficient flow can cause unstable operation of cylinders, manifested by vibrations or uneven movement, which negatively affects the precision of the operation.

Selection of the appropriate valve

To ensure optimal operation of the hydraulic system, it is important to select a valve with appropriate throughput, adapted to the requirements of a specific application. You should consider: Maximum flow in the system: The valve should be able to handle the maximum oil flow to avoid restrictions and potential damage. Working pressure: It is important that the valve is adapted to work at the pressures occurring in a given hydraulic system. Number and type of sections: Depending on the number of recipients and the nature of their work, you should choose a valve with the appropriate number of sections and functions, such as floating sections or sections with detents.
