Load-Sensing Hydraulic Manifold
Load-Sensing Hydraulic Manifold, QFZMG32H
The QFZMG32H load-sensing hydraulic manifold is designed for high-pressure, high-flow hydraulic systems. It adopts a full load-sensing control concept based on the LUDV principle, achieving proportional flow distribution among multiple actuators through load pressure compensation. This design is well suited for construction machinery hydraulic systems that require continuous combined motions and stable flow distribution, and it supports both hydraulic proportional control and electronic proportional control.
Features & Advantages
- LUDV flow distribution mechanism: When system flow is insufficient, flow is distributed proportionally among actuators, maintaining continuity of combined operations.
- Proportional control with fine adjustment: Proportional control is supported, and flow can be finely adjusted through spool stroke limiting.
- System stability design: Integrated secondary pressure relief valves and load pressure compensators provide high repeatability and low hysteresis characteristics.
- System-level tuning capability: Supports low-power unloading functions and customizable flow characteristics of the directional sections, enabling effective matching to different operating conditions.
