Advantages and features of Rexroth hydraulic control valves

‌High-precision control‌

Built-in closed-loop feedback system (such as LVDT/Hall sensor) and PID adjustment algorithm, the control accuracy can reach ±1%, suitable for high-precision scenarios such as CNC machine tool magazine positioning.

Supports analog input (0-10V or 4-20mA) and digital signal conversion, can dynamically adjust the valve core displacement, and realize linear adjustment of flow and pressure.

‌Energy saving and response speed‌

The maximum working pressure is 350 bar, the flow covers 10-120 L/min (depending on the diameter), and the response time is ≤20 ms, which is suitable for high-speed start and stop and dynamic load change requirements.

Proportional control technology can adjust the output power according to the actual load, reducing the overflow energy consumption by more than 30% compared with traditional hydraulic valves.

‌Anti-pollution and durability design‌

The dry servo motor and wear-free valve core reset structure are used to avoid hydraulic oil contamination of key components and extend the service life.

The valve core integrates a hydraulic force compensation mechanism to reduce the impact of pressure fluctuations on control accuracy and adapt to impact load conditions.

‌Modularity and intelligence‌

Integrated OBE electronic components (such as VT-DFPE series), no external amplifier required, supports multi-stage ramp control and characteristic curve correction functions, and simplifies system integration.

Equipped with LED status display and fault diagnosis interface, it can monitor overcurrent, signal abnormality and other problems in real time to improve maintenance efficiency.

‌Environmental adaptability‌

The protection level reaches IP67, and the valve body is nitrated/anodized. It can operate stably in an environment of -20℃ to +80℃ and withstand harsh conditions such as dust and vibration.

Compatible with a variety of media such as mineral oil and water-based hydraulic oil, the sealing material can be selected from NBR, fluororubber or PTFE, suitable for different industrial scenarios.

Precautions for use

‌Installation and commissioning specifications‌

During installation, it is necessary to ensure that the oil port meets the ISO 4401 standard, and the centering accuracy deviation of the valve body and the pipeline is ≤0.1 mm to prevent mechanical stress from damaging the valve core.

During the commissioning stage, the zero position and control curve need to be calibrated by fine-tuning the potentiometer to avoid overshoot or oscillation.

‌Power supply and signal management‌

The power supply voltage must strictly match 24V DC (±20% range), and it is recommended to configure filters and reverse polarity protection devices.

Signal lines (such as encoder feedback) must be routed separately with shielded cables, away from power cables to reduce electromagnetic interference.

‌Maintenance and troubleshooting‌

The first-level filter needs to be cleaned or replaced every 2000 hours of operation, and the aging of the seals (such as hardening of NBR seals) needs to be checked.

In case of abnormal vibration or leakage, the valve core is stuck, the sensor signal drift or hydraulic oil contamination is checked first.

‌Safe operation‌

The system pressure must be cut off before manual emergency operation to prevent accidental action from causing equipment damage or personal injury.

In high temperature environments, the viscosity of the hydraulic oil needs to be monitored to avoid control failure caused by oil deterioration.

This series of control valves are widely used in injection molding machines, engineering machinery and automated production lines, and improve the energy efficiency and stability of industrial systems through intelligent control and reliable design.
