Cast Iron Material Hydraulic Synchronous Gear Flow Divider Without Relief Valve

Product Description
The synchronous hydraulic gear flow divider is a reversible hydraulic element used for flow diversion or collection.
It adopts structures such as floating side plates, zoned pressure balance, and secondary seals.

Compared with throttling flow divider and collector valves, the gear flow divider has the advantages of small flow loss, high efficiency, low leakage, and good integrated performance.

It is widely used in the hydraulic systems of walking machinery and industrial equipment such as excavators, telescopic boom cranes, hoists, drilling machines, and rolling mills. 

 
Advantages

1.More accurate: accuracy tolerance: ±1.5 ~ 2.5%( collecting valve: ± 4 ~ 5%),

2.More efficient, is not sensitive to oil viscosity, strong ability to resist pollution.

3.The division ratios are constant and are unaffected by the loads at the actuators.

4.They can be used to provide synchronised movement of unequally loaded cylinders.

No matter how harsh the application environment is, our products can be perfectly harnessed. 

FAQ:

Q1: What is the synchronization accuracy under equal loads? How much does accuracy improve with the overflow compensation version?
A: The standard non-compensated version has a synchronization error of ±2.5% to ±4%. The version with a built-in overflow and one-way compensation valve has an error of ≤±1.5%; the compensated model is recommended for applications involving high load pressure differentials or off-center lifting.

Q2: How should I choose between aluminum alloy and cast iron housings?
A: Aluminum alloy: Lightweight, good heat dissipation, suitable for low pressures (≤16 MPa); used in scissor lifts, sanitation vehicles, and small platforms.
Ductile iron: Withstands pressures of 21–25 MPa, wear-resistant and impact-resistant; used in mining equipment, construction machinery, and heavy-duty lifting equipment.

Q3: Is unequal flow division possible? For example, a 2:1 flow ratio between two circuits?
A: Yes. By customizing gear sets with different displacements per section, we can achieve multi-circuit proportional flow division (e.g., 2:1, 3:1, 4:1) for synchronizing cylinders of different bore sizes.
