Hydraulic systems enable the transmission of high forces and precise movements of technical components. A central component in hydraulic systems are flow dividers and flow combiners, which ensure an even distribution or merging of volume flows. In conjunction with other components, these components are responsible for the precise control of hydraulic systems.

In this article, you will learn how flow dividers and flow combiners work and in which areas of application they are used. We also reveal the advantages of ARGO-HYTOS components.

The general function of flow dividers and flow combiners

Flow dividers and flow combiners are used to precisely regulate the oil flow in hydraulic systems. A flow divider divides the input oil flow into two usually equal volume flows. This enables an even distribution of the hydraulic energy to several actuators. This is particularly important when the synchronized movement of two or more actuators is required.

Flow combiners combine the returning volume flows according to their division or combination ratio to form a discharge flow. This function is essential to combine the return flow from two actuators and ensure uniform movement. Different division ratios can be realized, which increases the flexibility of these components.

A major advantage of flow dividers and flow combiners is that they are largely independent of the load. Even with different load and pressure ratios, they work with high accuracy. This is why the components are mainly used in complex hydraulic applications where precise control is required.

Thanks to their ability to operate independently of load and pressure differences, flow dividers and flow combiners make a significant contribution to the stability of hydraulic systems.

What is the difference between flow dividers and flow combiners?

Flow dividers and flow combiners fulfill different functions in hydraulic systems. A flow divider distributes the input oil flow into two or more equal volume flows, allowing several actuators to be operated simultaneously and synchronously. This enables particularly smooth movement, for example of loading platforms or lifting platforms.

A flow combiner, on the other hand, combines the returning volume flows from several actuators into a single outgoing flow. This function synchronizes the movement of the actuators and ensures that they work evenly.

How do flow dividers and flow combiners from ARGO-HYTOS improve hydraulic systems

ARGO-HYTOS has various models of flow dividers and flow combiners in its portfolio that are characterized by high precision and reliability.

The SFD2F-B4/I flow divider and combiner is designed for volume flows of up to 40 l/min and operating pressures of up to 350 bar. It divides the input oil flow evenly and compensates for deviations using specially matched orifices and compensation springs. This enables a high level of accuracy, even with different loads and pressure ratios.

SFD2F-B4/I is ideal for applications where low volume flows are required and precise synchronization of the actuators is necessary.

The SFD2F-D4/I flow divider and combiner can handle volume flows of up to 150 l/min at 350 bar. Like the B4 model, the D4 also divides the oil flow evenly and ensures precise control of the return flows. Thanks to its robust design and high flow capacity, it ensures reliable synchronization of movements in larger hydraulic systems.

Both models are largely load-independent and offer high accuracy, even with load and pressure differences. These properties make them a reliable solution for various industrial applications. Further details and illustrations can be found in the data sheets.

A special variant in the ARGO-HYTOS portfolio are the so-called flow dividers with end position compensation. These special shapes compensate for the tolerances in the movement of the connected cylinders or motors in their end position. Without such compensation, differences in the end positions of the cylinders or motors could lead to uneven movements. The end position compensation ensures that the actuators operate reliably and with maximum precision at all times.

For which applications are flow dividers and flow combiners suitable in different industries?

ARGO-HYTOS flow dividers and flow combiners are used in numerous applications in the following areas:

• Construction machinery
• Agricultural machinery
• Industry

Their ability to precisely control and synchronize hydraulic systems makes them indispensable components in a wide range of industries.

In construction machinery, flow dividers and flow combiners are often used in synchronization controls. These ensure that two cylinders move back and forth evenly despite different loads.

A typical example is the raising or lowering of loading levels. Without synchronization, the cylinders could work at different speeds, which would cause the load to slip. Flow dividers ensure a smooth process and therefore increase the safety and efficiency of the machine.

Another area of application is the differential lock. It synchronizes the speed between two hydraulic motors. This application is particularly important in vehicles that have to drive on uneven or slippery surfaces.

For example, they ensure a smooth drive on snow, ice, slippery roads and mud. They do this by preventing one wheel from spinning while the other is stationary. This improves traction and ensures better control of the vehicle.

In agriculture, flow dividers and flow combiners help to increase the efficiency and performance of machines such as tractors and harvesters. They enable the hydraulic cylinders to move smoothly, resulting in more precise control and better utilization of the machines.

The hydraulic components are also used in industrial applications. In production systems, they ensure the even distribution of hydraulic energy, which increases the efficiency of the machines and extends their service life. The precise control of the oil flow by flow dividers and flow combiners means that the machines require less maintenance.

The use of flow dividers and flow combiners in various applications significantly improves the performance and reliability of hydraulic systems. The technical components are therefore responsible for higher productivity and a longer service life of the machines. This ultimately makes operation more profitable and efficient.
