Product details

I. Product Overview

The 4WRE10-2X electromagnetic proportional directional valve is a high-performance direct-acting proportional directional valve produced by Rexroth (Germany). This valve controls the position of the valve spool through proportional solenoids, enabling proportional control of flow rate and direction in hydraulic systems. It is widely used in industrial equipment requiring precise control of hydraulic parameters.

II. Model Interpretation

• 4WRE: Indicates the series of direct-acting proportional directional valves.

• 10: Represents the valve's port size as NG10 (i.e., 10-port size).

• 2X: Represents the valve's series number or version number, typically related to its installation and connection dimensions.

III. Key Features

1. Direct-acting Design: Drives the valve spool directly through proportional solenoids, ensuring fast response and high control accuracy.

2. Electrical Position Feedback: Built-in position sensors monitor the valve spool position in real-time, ensuring the output is proportional to the input signal.

3. Integrated Control Electrical Components (OBE): Some models (e.g., 4WREE) integrate control electrical components, simplifying system design and enhancing reliability.

4. Plate-mounted Connection Structure: The connection dimensions comply with ISO 4401 standards, facilitating easy installation and replacement.

5. Multiple Spool Functions Available: In addition to conventional spools, options such as V, U, and Q5-type spools are available to meet different application requirements.

6. High Precision and Reliability: The combination of precision machining and electrical feedback results in negligible hysteresis. High-performance proportional solenoids, position sensors, and specially designed amplifiers ensure excellent temperature drift characteristics.

IV. Technical Parameters

• Maximum Operating Pressure: Typically up to 315 bar (specific values may vary depending on the model and configuration).

• Maximum Flow Rate: Varies from 80 L/min to 180 L/min depending on the model.

• Power Supply Voltage: Usually 24V DC.

• Control Signal: Input signals can be selected as A1 or F1, with zero adjustment and ramp potentiometers for easy on-site adjustment.

• Mounting Face: Complies with ISO 4401 standards, facilitating connection with other hydraulic components.

• Weight: Ranges from 6.3 kg to 16 kg depending on the model and configuration.

V. Application Areas

The 4WRE10-2X electromagnetic proportional directional valve is widely used in various industrial equipment requiring precise control of hydraulic parameters, including but not limited to the following fields:

1. Injection Molding Machines: Used to control pressure and flow rate during the injection molding process, improving product quality and production efficiency.

2. Die-Casting Machines: Precisely controls the flow and pressure of molten metal during the die-casting process, enhancing casting quality.

3. Construction Machinery: Such as excavators and loaders, used to control the flow rate and direction of hydraulic systems for precise equipment operation.

4. Hydraulic Presses: Used to control the pressure and speed of hydraulic presses to meet different processing requirements.

5. Automated Production Lines: Precisely controls the actions of hydraulic actuators in automated production lines, improving the automation level and production efficiency of the lines.
