FAQ:

1. What pressure sensors work with 4WREE valves?
Rexroth’s HM series pressure sensors (e.g., HM18-1X/250-C-K35) or third-party sensors with 4-20 mA output are compatible for pressure feedback applications.

2. Can I add a position feedback sensor to a 4WREE valve?
Yes, optional position feedback sensors (inductive or potentiometric) can be installed to monitor spool position and enable closed-loop control.

3. What is the purpose of a bypass valve with 4WREE installations?
A bypass valve allows fluid to bypass the 4WREE during maintenance or emergency shutdowns, preventing system pressure buildup.

4. Are there protective covers available for 4WREE valves?
Yes, Rexroth offers IP65-rated protective covers for solenoid coils and electronics to shield against dust, moisture, and mechanical damage.

Application-Specific Questions

5. Can 4WREE valves be used in mobile hydraulic applications (e.g., excavators)?
Yes, compact models (NG 6-10) are suitable for mobile equipment, provided they are protected from vibration and extreme temperatures (use shock mounts if needed).
