Product Key Advantages
1. Pilot‑Operated Stable Precision Control
Two‑stage pilot amplification with main‑stage electrical position feedback delivers precise flow regulation independent of flow‑force disturbances. Hysteresis ≤1% and response sensitivity ≤0.5% ensure consistent closed‑loop performance for light‑to‑medium hydraulic systems.
2. Hassle‑Free Direct Interchangeability
Manufactured strictly to ISO 4401‑05‑05‑0‑05 NG10 mounting dimensions, with identical port layout and ±10V A1 electrical pin‑out matching Rexroth 4WRJE10 A1. Direct drop‑in installation without manifold re‑machining or rewiring, minimizing retrofit downtime.
3. Compact & Robust Industrial Durability
Lightweight 7.4 kg compact design with IP65 ingress protection withstands vibration, shock and standard industrial environments. Wide temperature tolerance and multiple pilot oil supply modes adapt to diverse circuit designs and space‑constrained installations.
4. Safety‑Focused Low‑Maintenance Design
Spring‑centered main spool automatically returns to neutral position upon de‑energization for safe system reset. Integrated OBE includes undervoltage and short‑circuit protection. Factory‑calibrated zero point and detachable mating connectors simplify on‑site maintenance.

Installation & Commissioning Guidelines
Installation Notes
- Thoroughly clean all oil ports and connecting surfaces before installation to prevent contaminants from entering the valve body.
- Confirm the control signal type (±10V voltage) and power‑supply voltage match the valve nameplate specifications before wiring.
- Tighten 4 mounting bolts evenly to the recommended torque (13.5–15.5 Nm for M6 screws) to avoid valve‑body deformation and internal leakage, complying with ISO 4401‑05‑05‑0‑05 NG10 mounting specifications.
- Ensure the tank line does not run empty. Install a preload valve (approx. 2 bar preload pressure) if required by installation conditions.
- Gradually ramp‑up system pressure during commissioning. Inspect for leakage and abnormal noise before switching to full‑load operation.
Safety Precautions
- Retain manual hydraulic override for backup safety during system retrofits.
- Fit pressure‑relief valves in the hydraulic circuit for overpressure protection.
- Implement emergency‑stop logic to de‑energize the proportional valve under fault conditions.
- Ensure hoses and hydraulic connections are rated for the system's maximum working pressure.
- Zero‑point adjustment shall only be performed by trained personnel.
FAQ
Q: What is the main difference between 4WRJE10 A1 and 4WRKE10 A1?
A: 4WRJE10 A1 is a cost‑effective pilot‑operated valve with 250 bar max pressure for general industrial systems. 4WRKE10 A1 is a heavy‑duty 350 bar valve for more demanding load scenarios. Both share pilot‑operated position‑feedback architecture.
Q: What pilot oil supply modes are available for 4WRJE10?
A: Four standard modes: external pilot & external return (MXY), internal pilot & external return (MPY), internal pilot & internal return (MPT), external pilot & internal return (MXT). Select based on your system circuit design.
Q: Can this valve directly replace Rexroth 4WRJE10 series?
A: Yes. It follows the same ISO 4401 NG10 mounting standard, identical port geometry, ±10V A1 electrical interface and hydraulic performance. It supports drop‑in installation on compatible manifolds. Please send your full part number for final compatibility confirmation.
Q: What about warranty and lead‑time?
A: All standard valves carry a 12‑month quality warranty from delivery date plus lifelong technical consultation. Standard 4WRJE10 A1 configurations ship within 2‑4 weeks after order confirmation.
