Key Differences & Selection Guide

  1. 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.

  2. 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.

  3. 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.

  4. Q: What are the characteristics of the "W" spool?

    A:​ The W-type (overlap) spool​ has a small dead zone at the center, providing smooth acceleration/deceleration and preventing actuator creep, making it ideal for applications requiring smooth starts and stops.

  5. 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 and precision spool, this valve requires clean hydraulic fluid (typically NAS 1638 Class 8 or ISO 4406 18/16/13 is recommended).
