Product Description
Rexroth 4WRLE Pilot-Operated Proportional Directional Valves
Product Overview:
The Bosch Rexroth 4WRLE series represents the pinnacle of pilot-operated proportional control technology. As a two-stage proportional directional valve featuring Integrated On-Board Electronics (OBE), it is specifically engineered for high-precision displacement, velocity, and directional control in high-flow hydraulic systems. By utilizing closed-loop feedback of the main spool position, the 4WRLE series ensures exceptional dynamic response and minimal hysteresis for 2026 high-end injection molding machines, heavy-duty presses, and metal processing centers.
Featured model: 4WRLE10W-Z80SJ-3X/G24K0/A1M and associated sizes.
Key Technical Advantages:
Two-Stage High Dynamics: The pilot-operated stage precisely drives the main spool, maintaining rapid response times even under extreme pressure drops and high flow rates (up to NG27).
Integrated OBE Digital Electronics: Factory-mounted amplifiers support standard A1 ($\pm 10\text{V}$) command signals, simplifying field wiring and maximizing EMI resistance in industrial environments.
Closed-Loop Spool Position Feedback: Internal high-precision LVDT sensors monitor the spool position in real-time, automatically compensating for system pressure fluctuations or oil viscosity variations.
Optimized 3X Design Platform: The latest 3X sequence optimizes internal flow channels to minimize pressure drop and enhance overall system energy efficiency.
Versatile Spool Functions (W/V/E): The W-Z80SJ designation represents specific symmetrical or asymmetrical spool logic, ideal for the precise synchronization of differential or double-acting cylinders.
