Rexroth 4WRVE Pilot-Operated Proportional Directional Valves

Product Overview:

The Bosch Rexroth 4WRVE series is a high-performance, two-stage pilot-operated proportional directional valve engineered for precise control in high-flow hydraulic systems. These valves feature Integrated On-Board Electronics (OBE) and utilize closed-loop spool position feedback for exceptional linearity and dynamic response. Available in Size 16 (NG16) and Size 25 (NG25), the 4WRVE series is the industry choice in 2026 for high-end die-casting machines, heavy-duty extruders, and metal processing systems, ensuring smooth and accurate execution through robust design and minimal hysteresis.

Featured models: 4WRVE16V1-120M-2X/G24K0/B5M-869, 4WRVE25V370M-2X/G24K0/B5M, and 4WRVE16V200M.

Key Technical Advantages:

• Integrated OBE Digital Electronics: The factory-mounted amplifier supports standard B5 ($\pm 10\text{V}$) command inputs, maximizing electromagnetic interference (EMI) resistance and simplifying field wiring.

• Two-Stage High Dynamic Response: The pilot-operated architecture ensures rapid switching speeds even under conditions of high pressure drop and large flow volumes.

• Closed-Loop Spool Position Feedback: Internal high-precision LVDT sensors monitor the main spool position in real-time, ensuring flow output remains independent of load pressure fluctuations.

• Optimized 2X Design Sequence: Utilizing the proven 2X design platform, internal channels are optimized to support high nominal flows (up to 370 L/min) while maintaining superior energy efficiency.

• Specialized Customization (-869): Offers tailored solutions like the -869 suffix for specific industrial requirements, ensuring compatibility with unique hydraulic fluids or extreme environments.
