Factory Supply Rexroth Lrdu2 Control Valve A11vlo190lrdu2 Pump Repair Parts

 

 

Advantages

-High-Pressure & High-Flow Capability
Designed for heavy-duty hydraulic systems, the A11VLO190LRDU2 handles nominal pressures up to 280 bar (peak pressure 350 bar) and features a large displacement (190 cm³/rev), making it suitable for high-load, high-flow applications.
Its robust structure ensures stable performance even under continuous high-pressure operation.
-Precision Load-Sensing Control (LRDU2 Mode)
The LRDU2 control configuration integrates load-sensing (LS) and pressure compensation, dynamically adjusting flow and pressure to match system demands. This minimizes energy loss and optimizes efficiency by delivering only the required power for the current load.
Enables stepless adjustment of flow rate, ensuring smooth and precise control of hydraulic actuators (e.g., cylinders, motors).
-Energy Efficiency & System Stability
Load-sensing technology reduces power consumption by up to 30% compared to fixed-displacement pumps, as it avoids unnecessary pressure build-up during low-load operations.
Pressure compensation maintains consistent flow regardless of pressure fluctuations in the system, enhancing stability for precision machinery.
-Durability & Reliability
Constructed with high-strength alloy steel components and wear-resistant coatings, the valve resists cavitation, corrosion, and mechanical fatigue.
Sealing systems are optimized for high-pressure applications, minimizing leakage and extending service life even in harsh environments (e.g., dust, vibration, temperature variations).
-Low Noise & Vibration
Hydrodynamically designed swashplate and piston assemblies reduce fluid pulsation, resulting in low operational noise (typically ≤75 dB) and minimal vibration-critical for operator comfort in enclosed cabins or noise-sensitive environments.
Flexible Integration & Maintenance
Complies with international mounting standards (e.g., ISO 3019-2) and port connections (SAE/JIC), allowing easy retrofitting into existing hydraulic systems.
Modular design simplifies maintenance, with replaceable components (e.g., seals, control cartridges) that reduce downtime and repair costs.

Applications
-Heavy Construction Machinery
Excavators, bulldozers, and crawler cranes: Controls boom, arm, and bucket movements with high precision, even when handling heavy loads or complex terrain.
Concrete pumps and pavers: Ensures stable hydraulic power for material and positioning systems.
-Mining & Quarrying Equipment
Underground and surface mining trucks, loaders, and drilling rigs: Handles extreme loads in rugged environments, providing reliable power for dumping, digging, and rock breaking.
Crushers and screening plants: Drives hydraulic cylinders for jaw adjustment and material processing.
-Industrial Manufacturing
Metal forming presses (e.g., forging, stamping): Delivers consistent high pressure for precise sheet metal shaping and heavy-duty forming operations.
Large-scale material handling systems (e.g., port cranes, conveyor drives): Enables smooth, high-torque motion control for heavy cargo lifting and transport.
-Marine & Offshore Engineering
Ship cranes, winches, and anchor systems: Withstands saltwater corrosion and high dynamic loads during cargo handling or ----offshore operations.
Offshore platform hydraulic systems: Powers drilling equipment, deck cranes, and safety systems in harsh marine environments.
-Renewable Energy & Heavy Equipment
Wind turbine maintenance cranes: Provides precise hydraulic control for lifting components during installation or repair.
Forestry machinery (e.g., log loaders, harvesters): Handles repetitive high-load cycles in forestry operations.

Summary
The A11VLO190LRDU2 valve balances high-pressure performance, energy efficiency, and precision control, making it a core component for heavy machinery and industrial systems that require reliable, high-load hydraulic power. Its durability and adaptability suit it for both mobile and stationary applications in demanding environments
