Product Key Advantages
1. Stable Long-Distance Large-Flow Control
The 4-20mA current loop signal maintains stable transmission even over hundreds of meters, paired with 180 L/min large flow capacity. Ideal for large workshops, long production lines and medium-heavy hydraulic systems with high electromagnetic interference.
2. Built-In Cable Break Safety Protection
Integrated cable break monitoring automatically shuts off the output stage when signal current drops below 1.5 mA, preventing uncontrolled equipment movement and reducing operational risks in harsh industrial environments.
3. Heavy-Duty Reliable Performance
IP65 ingress protection, wide temperature tolerance and robust construction ensure stable operation in dusty, high-vibration industrial sites, handling large flow and high pressure demands with long service life.
4. Straightforward Drop-In Interchangeability
Strictly manufactured to ISO 4401 NG10 standard with identical port dimensions and F1 interface pin assignments to equivalent Rexroth 4WREE10 F1 valves. Installs directly into existing compatible manifolds without re-machining.

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 (4–20mA current) and power supply voltage match the valve nameplate specifications before wiring.
- Tighten mounting bolts evenly to the recommended torque to avoid valve body deformation and internal leakage, in accordance with ISO 4401-05-04-0-05 NG10 mounting standards.
- Gradually increase system pressure during commissioning. Monitor for leaks and abnormal noise before full-load operation.
Safety Precautions
- Maintain manual hydraulic override capability during system retrofit for backup safety.
- Install pressure relief valves in the hydraulic circuit to protect against overpressure.
- Add an emergency stop circuit that de-energizes the proportional valve in emergency situations.
- Ensure all hydraulic connections and hoses are rated for your system's maximum working pressure.
FAQ
Q: What is the difference between 4WREE10 F1 and 4WREE6 F1?
A: 4WREE10 F1 (NG10) supports up to 180 L/min max flow for medium-large systems; 4WREE6 F1 (NG6) supports up to 80 L/min max flow for small-to-medium equipment. Both feature 4-20mA current control with strong anti-interference performance.
Q: Does the F1 valve have cable break protection?
A: Yes. When the signal current drops below 1.5 mA, the output stage automatically shuts off to ensure equipment and operator safety.
Q: Do you provide on-site installation guidance?
A: Yes. We offer remote technical guidance for all standard orders, and on-site commissioning support for bulk project orders.
Q: What is the warranty period?
A: All standard valves come with a 12-month quality warranty from the delivery date, with lifelong technical consultation support.
