Load-Sensing Hydraulic Manifold
Load-Sensing Hydraulic Manifold, QFZMG14H
The QFZMG14H load-sensing hydraulic manifold is designed based on the LUDV principle, enabling load-pressure-independent flow distribution between individual valve sections. This makes it suitable for hydraulic systems that require proportional consistency during combined operations.
A compact sectional structure is adopted, allowing different valve assemblies to be formed as required. Compatibility with both fixed displacement pumps and variable displacement pumps makes the valve suitable for a wide range of hydraulic control applications.
