Frequently Asked Questions
1. What safety precautions should be taken when installing 4WREE valves?
Depressurize the hydraulic system before installation, wear protective gloves and goggles, and ensure the valve is rated for the system's pressure and flow.
2. Are 4WREE valves RoHS compliant?
Yes, all models comply with the Restriction of Hazardous Substances (RoHS) Directive (2011/65/EU), restricting lead, mercury, and other hazardous materials.
3. What is the maximum pressure drop across a 4WREE valve?
Maximum pressure drop is 20 bar (290 psi) for NG 6-10 models and 15 bar (217 psi) for NG 16-25 models to avoid overheating.
4. Can 4WREE valves be used in safety-related systems?
Yes, when paired with appropriate safety components (e.g., redundant valves, safety controllers), they can be used in Safety Integrity Level (SIL) 2 applications (per IEC 61508).
Replacement & Spare Parts
5. How to identify the correct replacement 4WREE valve?
Use the full part number (e.g., 4WREE 10 E75-2X/G24K31/A1V), which includes size, flow rate, voltage, and options. Cross-reference with Rexroth's catalog or contact customer service.
