Q: What is the main difference between 4WREE and 4WRAE?
A: The 4WREE series has LVDT feedback (closed-loop spool position control), offering higher accuracy and repeatability. The 4WRAE series (e.g., R900954083) has no LVDT (open-loop force control), making it less precise but more cost-effective.
Q: What does the "E" spool mean?
A: The E spool is a critical center (zero overlap) spool. It provides a direct relationship between the control signal and the opening area, offering good metering characteristics for general directional and flow control.
Q: Does this valve require an external amplifier?
A: No. The 4WREE designation and /G24K31 suffix indicate that the valve has Integrated On-Board Electronics (OBE). The amplifier is built into the valve coil, so you only need to provide a 24V DC power supply and a ±10V control signal.
Q: What is the control signal for this valve?
A: The /A1 suffix explicitly indicates a ±10 V DC analog voltage input. If you need a 4–20 mA current input, you would need the /F1 version.
Q: Is the mounting compatible with other NG10 valves?
A: Yes. The "2X" series uses the standard ISO 4401-05-04-0-05 mounting interface for NG10 valves. It is directly interchangeable with other NG10 "2X" series valves.
Q: What is the critical installation note?
A: Ensure the T port (tank) is connected to the tank without significant backpressure. Since this valve has integrated electronics and LVDT, ensure a stable 24V DC power supply to avoid voltage drops that can affect the closed-loop control performance.
