Rexroth 4WREE Series Proportional Valves with LVDT Feedback

Product Overview:

The Rexroth 4WREE Series is a direct-operated proportional directional valve featuring On-Board Electronics (OBE) and LVDT position feedback. Engineered for closed-loop systems requiring high repeatability and dynamic performance, the LVDT sensor monitors spool position in real-time. This allows the system to compensate for flow-force disturbances automatically, ensuring superior linear control under various pressure conditions. Available in both compact Size 6 and high-flow Size 10, the 4WREE is the premier choice for injection molding, press technology, and factory automation.

Featured models include the high-dynamic 4WREE6E and the high-flow 4WREE10E.

Key Technical Advantages:

• Integrated Electronics (OBE): On-board amplifiers simplify wiring and enhance Electromagnetic Compatibility (EMC) for robust performance.

• Precision Position Feedback: The inductive LVDT sensor ensures spool alignment with the command signal, minimizing hysteresis.

• Plug-and-Play Setup: Factory-calibrated gain and null settings significantly reduce onsite commissioning time.

• Diverse Spool Options: Available in E (closed center), W (relief center), and other configurations to fit specific circuit logic.
