FAQ:

6. What mounting standards apply to 4WREE valves?
Most 4WREE models comply with ISO 4401 (CETOP RP 121 H) mounting dimensions, ensuring interchangeability with other standard valves.

7. Can 4WREE valves be mounted in any orientation?
While vertical mounting is recommended for optimal performance, valves can be mounted horizontally with minimal impact, provided the solenoid coils are not exposed to direct moisture or extreme temperatures.

8. What torque should be used for mounting bolts?
Follow Rexroth’s specifications: M10 bolts require 25-30 Nm, M12 bolts require 45-55 Nm, and M16 bolts require 90-110 Nm (always use thread lock if specified).

9. How to ensure proper alignment during installation?
Use alignment pins (where provided) and ensure the valve flange is clean and flat; misalignment exceeding 0.1 mm may cause leakage or reduced performance.

10. Is a relief valve required for 4WREE installations?
Yes, a relief valve must be installed in the system to protect the valve and hydraulic components from overpressure, set to 10-15% above the maximum operating pressure of the 4WREE.
