4WRPEH6C3B04P-2X/G24K0/A1M Rexroth Prop. Valve

Product Overview

The 4WRPEH6C3B04P-2X/G24K0/A1M and 4WRPE10E80SJ-2X/G24K0/A1M are Bosch Rexroth high-response proportional directional valves with electrical position feedback and integrated on-board electronics (OBE). The 4WRPEH6 is a direct-operated servo solenoid valve in size NG6 with nominal flow of 4 L/min (at Δp=70 bar) and maximum operating pressure of 315 bar. The 4WRPE10 is size NG10 with nominal flow of 80 L/min. These valves offer true interchangeability as drop-in replacements for original Rexroth units without manifold modifications. Every unit undergoes precision machining and 100% simulated duty-cycle testing to ensure high-precision position/velocity/force control, low hysteresis and fast response.

Key Technical Advantages:

1. Integrated OBE with closed-loop position feedback – Built-in electronics and position sensing deliver low hysteresis and high repeatability for closed-loop control.
2. High-response direct-operated design – Fast dynamic response suitable for precise position, velocity and force control.
3. True interchangeability and standard interfaces – Fully compliant with ISO 4401 mounting pattern, enabling direct replacement of original Rexroth valves.
4. Precision machining and reliable performance – Steel-sleeve spool construction verified by 100% duty-cycle testing for long-term stable operation.

Application Areas

Ideal for injection molding machines, die-casting equipment, test stands, machine tools, servo-hydraulic systems and any industrial closed-loop hydraulic application requiring high-precision position, velocity or force control.

Expert Maintenance Tips

Ensure the manifold is flat and clean during installation; make reliable electrical connections with proper earthing; maintain fluid cleanliness at ISO 4406 18/16/13 or better; periodically check position feedback signals; confirm command-signal zero point on first power-up; after prolonged storage, energize the valve to verify operation.
