LT-PSV/PSL (Load-Sensing System)
The LT-PSV/PSL series load-sensing hydraulic manifold is designed based on the load-sensing (LS) control principle. By dynamically adjusting system oil supply according to load feedback, the system flow is matched to actuator demand. The series is mainly used for control applications in construction machinery, mining machinery, agricultural machinery, coal mining equipment, and metallurgical machinery, and is suitable for hydraulic systems with requirements for energy efficiency and stable control performance.
Features & Advantages
- Load-sensing adaptive control: System oil supply is regulated according to actuator load variation, reducing pump load and overall energy consumption.
- Low-power unloading function: Energy loss and system heat generation are reduced under light-load or idle operating conditions.
- Multiple control options: Supports manual control, hydraulic pilot control, electric control, and CAN bus control, facilitating integration with different control systems.
- Series-based configuration: A wide range of port sizes, flow ratings, and section combinations are available to suit hydraulic systems of different scales and capacities.
