The main characteristics and functions of the Rexroth high-frequency directional valve from Germany are as follows:

High performance and high precision: Rexroth high-frequency directional valve adopts excellent high-frequency response technology, which can achieve faster response speed and higher control accuracy.

Precise control: This directional valve adopts excellent proportional control technology, which can achieve precise control of flow and direction in the hydraulic system. Its response speed reaches the millisecond level, which can meet the requirements of high-speed mechanical motion control.

Flow control capability: Rexroth high-frequency directional valve from Rexroth has high-precision flow control capability, which can achieve precise flow control under different working pressures. It has excellent dynamic characteristics and small steady-state errors.

Fault detection and alarm mechanism: The Rexroth 4WRPEH directional valve is also equipped with * fault detection and alarm mechanism, which can detect and alarm in a timely manner when abnormal situations occur, ensuring the safety and reliability of the system.

Electro hydraulic conversion and power amplification: The Rexroth guided high-frequency directional valve electro-hydraulic servo system is a feedback control system composed of an electrical signal processing device and a hydraulic power mechanism. The most common ones are electro-hydraulic position servo system, electro-hydraulic speed control system, and electro-hydraulic force (or torque) control system. It is a typical electro-hydraulic position servo control system. The feedback potentiometer and command potentiometer in the figure are connected to form a bridge circuit. The feedback potentiometer sliding arm is connected to the control object, and its function is to convert changes in the position of the control object into changes in voltage. The potential difference between the feedback potentiometer and the instruction potentiometer sliding arm (reflecting the deviation between the control object position and the instruction position) is amplified by an amplifier and applied to the electro-hydraulic servo valve to convert it into a hydraulic signal, which drives the hydraulic cylinder piston and drives the control object to move in the direction of eliminating the deviation. When the deviation is zero, the drive stops, so that the position of the controlled object always changes according to the law given by the command potentiometer.

In summary, the Rexroth high-frequency directional valve from Germany plays a crucial role in industrial automation and fluid control. Its high performance, high precision, and reliable fault detection and alarm mechanism make it an ideal choice for many applications.

The use and maintenance of the German ReXROTH high-frequency directional valve mainly include the following aspects:

Easy to operate and maintain: This directional valve is designed with a detachable fan and LCD display control panel, making it convenient for users to operate and maintain.

Function and high performance: The power connection voltage is 3AC380... 480V, the frequency is 47... 63Hz, and the DC bus voltage is the DC power supply voltage value x1.41. It is equipped with a braking chopper/resistor, which can provide different braking powers.

Reliable Quality and Global Service: The Rexroth brand is renowned for its reliable quality and global service.

The correct adjustment method: Place the vehicle on a flat surface with no load, adjust the load sensing spring so that there is no gap between the lever and the piston. If conditions permit, the pressure distribution characteristic curve can be drawn by measuring the pressure of the front and rear wheel brake pipelines to confirm whether the adjustment is qualified.

In summary, when using the German ReXROTH high-frequency directional valve, attention should be paid to its ease of operation, maintenance convenience, high quality standards, and global service system. At the same time, for specific adjustments and maintenance work, the correct methods mentioned above should be followed to ensure the normal operation of the equipment and extend its service life.
