Key Differences & Selection Guide
-
Q: What is the core difference between 4WREE and 4WRAE series?
A: The 4WREE series features LVDT feedback (closed-loop control), offering high precision and better contamination resistance. The 4WRAE series (e.g., R900954083) has no LVDT (open-loop), making it more cost-effective but with lower accuracy and repeatability.
-
Q: What is the control signal interface?
A: The suffix /A1 indicates a ±10 V DC analog voltage command input. For a 4–20 mA current signal, select the version with the /F1 suffix.
-
Q: Is an external amplifier required?
A: No. The "E" in the model and the /G24K31 suffix indicate the valve has Integrated On-Board Electronics (OBE). It only requires a 24V DC power supply and the command signal to operate.
-
Q: What are the characteristics of the "E" spool?
A: The E-type (zero overlap/critical center) spool provides good linearity around the center position, fast response, and is suitable for applications requiring precise flow control and rapid directional changes.
-
Q: What are the critical installation considerations?
A: Ensure the tank (T) port return line pressure does not exceed 210 bar. Due to its closed-loop design, this valve requires clean hydraulic fluid (typically NAS 1638 Class 8 or ISO 4406 18/16/13 is recommended).
