Rexroth 4WRLE Pilot-Operated Proportional Directional Valves

Product Overview:

The Bosch Rexroth 4WRLE 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 electrical spool position feedback for closed-loop control, delivering exceptional repeatability and dynamic stability. Available in NG10, NG16, and NG25 nominal sizes, the 4WRLE series is the industry choice in 2026 for high-end injection molding machines, heavy-duty extruders, and metal processing centers requiring smooth flow transitions and synchronized movements.

Featured models: 4WRLE10V85M-3X/G24K0/A1M and 4WRLE16X200M-3X/G24K0/A1M-811.

Key Technical Advantages:

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

• Integrated OBE Electronics: The factory-mounted digital amplifier supports standard A1 ($\pm 10\text{V}$) command inputs, simplifying field wiring and maximizing EMI resistance.

• Spool Position Feedback: An internal high-precision inductive position transducer ensures spool positioning is independent of system pressure fluctuations or variations in oil viscosity.

• Optimized 3X Design Sequence: The latest 3X platform incorporates optimized fluid dynamics to reduce internal pressure drop and enhance overall system energy efficiency.

• Versatile Spool Functions (V/X/W): Offers various symmetrical and asymmetrical spool logic to match different actuators such as differential cylinders and double-acting cylinders.
