Rexroth 3WRCE Series Two-Stage High-Performance Proportional Servo Valves

Product Overview:

The Rexroth 3WRCE Series is a two-stage proportional directional valve with On-Board Electronics (OBE), engineered for closed-loop control of position, velocity, and pressure in heavy-duty industrial hydraulic systems. Covering nominal sizes from NG40 to NG50, the 3WRCE series utilizes a precision pilot stage to actuate the main spool, coupled with a high-accuracy position feedback system to maintain servo-grade dynamic response even under high-flow conditions. It is the premier choice for aluminum extrusion presses, large hydraulic forming machines, and metallurgical production lines.

Featured models on this page include the R901147272 (3WRCE50) and R901056312 (3WRCE40).

Key Technical Advantages:

• Ultra-High Flow Capacity: Specifically designed for NG40 (460L) and NG50 (720L) sizes to meet the rapid actuation demands of large-scale actuators.

• Integrated On-Board Electronics (OBE): The control unit is integrated onto the valve body, simplifying system wiring and providing industry-leading Electromagnetic Compatibility (EMC).

• Two-Stage Feedback Architecture: Seamless coordination between the pilot and main stages provides exceptional frequency response bandwidth for complex dynamic tracking.

• Precision Null Design: Features a micro-ground spool with excellent null stability, making it ideal for high-performance closed-loop systems.
