Load-Sensing Hydraulic Manifold
Load-Sensing Hydraulic Manifold, QFZMG12H
The QFZMG12H load-sensing hydraulic manifold is designed based on the pre-compensation load-sensing (LS) principle. It delivers the required flow according to actuator demand while maintaining actuator speed independent of load variation. This design is suitable for construction machinery hydraulic systems that require high inching performance and precise control, and it supports multiple control methods to meet different system configuration requirements.
Features & Advantages
- Pre-compensation load-sensing control: Stable flow supply is achieved through load feedback, making the valve suitable for fine and precise motion control.
- Excellent inching performance: Enhances controllability and accuracy under low-speed and small-stroke operating conditions.
- Energy-efficient design: Under load-sensing control, system energy loss and power consumption are effectively reduced.
