Product Key Advantages

1. Strong Anti‑Interference for Long‑Distance Large‑Flow Control

The 4‑20 mA current‑loop signal delivers stable transmission over long cable runs and maintains immunity against EMI from motors and frequency converters. Built‑in cable‑break monitoring automatically shuts down output stage at signal current below 2 mA to prevent uncontrolled machine motion. Optimized for medium‑to‑large flow (50‑100 L/min) heavy‑duty hydraulic equipment in electrically‑noisy production environments.

2. Hassle‑Free Direct Interchangeability

Manufactured strictly to ISO 4401‑05‑04‑0‑05 NG10 mounting dimensions, with identical port layout and F1 electrical pin‑out matching Rexroth 4WRPEH10 F1. Direct drop‑in installation without manifold re‑machining or rewiring, minimizing retrofit downtime and project costs.

3. Servo‑Grade Medium‑Large‑Flow Precision Control

Servo‑quality matched spool‑and‑sleeve assembly achieves hysteresis ≤0.2% and excellent temperature stability (zero‑shift <1% over Δϑ = 40 °C). It guarantees repeatable closed‑loop position, velocity and pressure regulation for large‑capacity hydraulic test rigs and forming machinery.

4. Safe & Energy‑Efficient Industry‑4.0‑Ready Design

Direct‑acting construction eliminates pilot‑oil supply requirements to cut system energy consumption and piping complexity. Spring‑centered spool returns to defined fail‑safe neutral position upon power loss or cable‑break fault. Optional IO‑Link interface enables remote parameter setting, real‑time condition monitoring and safety shut‑off up to PL d / Category 3 according to EN 13849‑1.

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 (4‑20 mA current‑loop) and power‑supply voltage match the valve nameplate specifications before wiring. Use shielded twisted‑pair cables for signal wiring; ground shield at one end. Ensure total loop resistance stays ≤500 Ω.
Tighten mounting bolts evenly to recommended torque to avoid valve‑body deformation and internal leakage, complying with ISO 4401‑05‑04‑0‑05 NG10 mounting specifications.
Gradually ramp‑up system pressure during commissioning. Inspect for leakage and abnormal noise before switching to full‑load operation. Verify cable‑break‑protection function by simulating signal disconnection.

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.

FAQ

Q: What is the maximum transmission distance for the 4‑20 mA F1 signal?

A: With standard 24 VDC supply and 1.5 mm² shielded twisted‑pair cable, stable signal transmission can reach up to 500 meters for large‑workshop layouts. Keep total loop resistance ≤500 Ω.

Q: Does 4WRPEH10 F1 support cable‑break protection?

A: Yes. Built‑in cable‑break monitoring triggers output‑stage shutdown when input current drops below 2 mA, preventing uncontrolled equipment movement and improving machine safety.

Q: What differentiates 4WRPEH10 F1 from 4WRPEH6 F1?

A: 4WRPEH10 F1 is NG10 large‑flow variant (50‑100 L/min) for medium‑large hydraulic machinery. 4WRPEH6 F1 is NG6 small‑flow (4‑40 L/min) for compact precision equipment. Both share <10 ms response and optional IO‑Link capability.

Q: Can IO‑Link be retrofitted on‑site for standard F1‑version valves?

A: IO‑Link hardware is factory‑integrated during manufacturing. Please specify IO‑Link requirement at order placement; field retrofitting is not supported.

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 4WRPEH10 F1 configurations ship within 2‑4 weeks after order confirmation.
