II. Product Features

1. Direct-Acting Design

• Operated directly by a proportional solenoid, ensuring fast response and high control accuracy.

• The proportional solenoid has a central thread, and the coil can be removed independently for easy maintenance and replacement.

2. Electrical Position Feedback

• Integrated position sensor provides real-time feedback on the spool position, ensuring accurate control.

• Optional integrated electronic control (OBE) simplifies electrical connections and enhances system stability.

3. Multiple Control Modes

• Supports external electronic control (4WRE type) or integrated electronic control (4WREE type) to meet diverse application requirements.

• Flow and pressure can be adjusted by varying the input electrical signal (e.g., 0-10V, 4-20mA).

4. High Pressure and Large Flow Capacity

• Maximum operating pressure:315 bar, suitable for high-pressure hydraulic systems.

• Maximum flow rate:180 L/min(size 10), ideal for large-flow applications.

5. Energy Efficiency and Environmental Friendliness

• Advanced energy-saving design reduces power consumption and system heat generation.

• Complies with environmental standards, ensuring eco-friendly operation.

V. Operation and Maintenance

1. Operation

• Before operation, carefully read and understand the operating instructions and safety precautions in the product manual.

• Set appropriate control parameters (e.g., input signal range, proportional valve gain) based on actual requirements.

• Perform necessary commissioning and testing before starting the system to ensure proper valve operation.

2. Maintenance

• Regularly inspect the valve’s exterior and connections for damage or leaks.

• Clean the valve’s filter screen and filters periodically to prevent contaminants from entering the valve body and affecting performance.

• Check the electrical connections regularly to ensure they are secure and reliable.

• If replacing components such as the proportional solenoid or position sensor, use genuine parts and follow the instructions in the product manual.
