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.
