Cast Iron Gear Type Flow Divider Without Relief Valve

In a multi-section gear unit, the sections are rigidly connected coaxially and synchronized through positive-displacement mechanical action. The incoming oil flow is distributed among multiple outlets—either equally or in specific proportions—based on fixed displacement ratios. The meshing of the gears ensures that a precise, fixed volume of fluid is discharged with every revolution. The unit is capable of both flow division and flow combination (collection). The main housing does not include independent relief valves or check valves for individual outlets, nor does it feature built-in compensation channels for unloading at the end of a stroke.

Product Introduction

Gear synchronous flow divider motor without built-in relief valve. Positive displacement mechanically forced synchronization by rigid coupled gear sets. Stable dividing accuracy, low pressure drop and low heat generation. Bi-directional for flow dividing and flow collecting.

 

Advantages

1. Compact structure, smaller footprint, and lower cost; the simplified internal flow path minimizes potential failure points, making it ideal for external valve manifold configurations where customers can customize their own hydraulic circuits.
2. High synchronization accuracy: ±1.5% to ±3% (under similar load conditions and minimal pressure differential). Features precision-ground gears and axial clearance compensation, resulting in low internal leakage-perfect for long-term, constant-speed synchronization.
3. Bidirectional functionality: Capable of both flow division and flow combining; can also serve as a simple pressure-intensification unit.
4. Easy maintenance: Contains no internal pressure-regulating springs or valve spools, and has relatively flexible requirements regarding hydraulic fluid cleanliness and pressure tolerances.

Applications
Foundry, lifting platforms, agricultural machinery, metallurgy, hydraulic fixtures, synchronized movement

 

FAQ
Q: How should I choose between a synchronous motor without relief valves and one with built-in relief valves?
A: If the load is evenly distributed, there is no risk of one cylinder reaching its end-of-stroke position before the others, and you already have an external protection circuit in place, choose the version without relief valves. If you require automatic alignment of the cylinders at the end of their stroke, anticipate significant uneven loading, or wish to simplify your hydraulic circuit, choose the version with built-in relief and make-up valves for each section.
