HBS flow dividers

Flow dividers / combiners are used in hydraulic systems to split the oil flow from one supply line into two equal or proportional outlet flows. They enable synchronous movement of multiple actuators without mechanical linkage and ensure stable operation under varying load conditions.

Function of flow dividers / combiners

Flow dividers distribute the incoming flow according to a fixed ratio defined by the internal orifice diameters of the valve. The flow split is therefore not adjustable.

These valves are typically used when:

Two actuators of equal dimensions must move simultaneously
Both actuators are supplied by the same pump and controlled by one directional valve
Synchronous extension is required without load influence between actuators, such as in load platforms or scaffolding systems

By maintaining balanced flow distribution, flow dividers ensure predictable and synchronised actuator movement in mobile and industrial hydraulic applications.

Flow dividers and combiners in hydraulic systems

Flow dividers, also known as flow divider / combiners, are used in hydraulic systems to split the oil flow from a single inlet line into two equal or proportional outlet flows. This allows multiple actuators to operate simultaneously while maintaining stable and predictable movement.

The division ratio is determined by the internal orifice diameters of the valve. As a result, the flow split is fixed and not adjustable.

Operating principle and flow distribution

These valves divide the incoming flow mechanically into two separate outlet flows. Because the internal geometry defines the distribution ratio, each outlet receives a consistent portion of the total flow regardless of load differences between the connected actuators.

By ensuring balanced flow distribution, the valve allows connected components to move synchronously without one actuator influencing the speed or movement of the other.

Typical applications for flow dividers

Flow dividers are commonly used in hydraulic circuits where two actuators must move in and out at the same time without being rigidly linked to each other.

Typical applications include:

Two actuators of identical dimensions, supplied by the same pump and controlled by a single directional valve
Systems where actuators must operate independently of each other’s load
Synchronous extension of two linear actuators connected to a common load, such as load platforms or scaffolding systems

These applications benefit from stable synchronisation and predictable motion control.

Flow dividers within the HBS product range

HBS flow dividers are designed for integration into both mobile and industrial hydraulic systems. They can be combined with other hydraulic components such as pressure relief valves, pressure reducing valves and directional control valves.

Their robust design and reliable flow splitting make them suitable for OEM applications as well as retrofit installations where synchronised actuator movement is required.
