Product Description
4WREE Series Proportional Valves with Integrated Electronics (OBE)
Product Overview: The 4WREE series represents the premium standard in electro-hydraulic proportional control, specifically designed for hydraulic systems requiring high-precision control over position, velocity, and pressure. As a direct-operated proportional valve, it integrates On-Board Electronics (OBE) and a spool position feedback sensor (LVDT) to monitor and correct spool displacement in real-time. This closed-loop control structure drastically reduces hysteresis and significantly enhances the system’s dynamic response frequency, making it a preferred choice for plastic machinery, machine tool control, and automated production lines.
Featured models: 4WREE6E16-2X/G24K31/A1V, 4WREE10W1-75-2X/G24K31/A1V, and supporting specs E32, E08-20, V16-2X, 10E-75-22.
Key Technical Advantages:
Integrated OBE Actuation: Eliminates the need for external amplifier cards. Features a standard 7-pin (6+PE) connector for direct control and superior EMI resistance.
Closed-Loop Feedback: Utilizes an LVDT displacement sensor for closed-loop spool control, ensuring high linearity and consistency between the command signal and flow output.
High Dynamic Frequency Response: Optimized solenoid thrust design supports high-frequency switching, ideal for precision injection molding or pressure compensation systems.
Full Voltage & Signal Compatibility: Standard G24 (24V DC) power supply, supporting ±10V voltage or 4-20mA current signal control interfaces.
