Rexroth 4WRTE Valve | 4WRTE32V-600L | 4WRTE16V1-200L | 4X Series | Proportional Directional Valve

Rexroth 4WRTE Pilot-Operated Proportional Directional Valves

Product Overview:

The Bosch Rexroth 4WRTE series represents the pinnacle of hydraulic control technology, engineered for industrial applications requiring high flow rates and extreme dynamic response. These valves feature Integrated On-Board Electronics (OBE) and utilize dual electrical position feedback for the pilot stage and main spool to achieve closed-loop control. Available in NG16 and ultra-high-flow NG32 sizes, the 4WRTE series provides unrivaled linearity and repeatability for 2026 high-end die-casting machines, heavy-duty forging equipment, and steel production lines.

Featured models: 4WRTE32V-600L-4X/6EG24K31/A1M and 4WRTE16V1-200L-4X/6EG24EK31/F1M.

Key Technical Advantages:

• Pilot-Operated Closed-Loop Control: A high-performance pilot stage drives the main spool, integrated with LVDT sensors for real-time position feedback, significantly reducing hysteresis.

• Integrated OBE Digital Electronics: The factory-mounted amplifier supports A1 ($\pm 10\text{V}$) or F1 (4-20mA) command signals, maximizing EMI resistance and simplifying system wiring.

• Optimized 4X Design Sequence: Utilizing Rexroth’s latest 4X series iteration, the internal channels are optimized to support high nominal flows (up to 600 L/min) while maintaining an excellent energy efficiency ratio.

• High Dynamic Response: Specifically designed for rapid cycle conditions with minimal step response times, ensuring precise starting, stopping, and synchronization of actuators.

• Industrial-Grade Durability: Robust valve body construction combined with IP65-rated protection ensures long-term stable operation in harsh environments involving high heat, vibration, and dust.
