Q: What is the practical difference between the "W" spool and the "E" spool?
A: The "W" spool has overlap (positive overlap), meaning there is a small dead zone around the center position where no flow occurs. This provides good metering control for velocity control appliions and is more robust against contamination. The "E" spool is zero-overlap (critical center), offering higher resolution and linearity, making it better for precise position control in closed-loop systems.
Q: Can I use this valve with a 4–20 mA signal?
A: No. The suffix /24A1 specifies a ±10 V voltage input. If your controller outputs 4–20 mA, you need the /24F1 version (e.g., R901523727). Applying a current signal to an A1 valve will not function correctly.
Q: Why is the maximum pressure 315 bar instead of 350 bar like some other 4WREE valves?
A: The pressure rating is spool-dependent. The W16 spool variant is typically rated for 315 bar, while E-spool variants (E16, E32) are often rated for 350 bar. Always check the specific datasheet for your order number to confirm the rated pressure for your appliion.
Q: Does the "3X" series affect compatibility with my existing manifold?
A: No, it ensures compatibility. The "3X" (component series 30-39) indies standardized mounting dimensions per ISO 4401-03. This valve can be directly interchanged with any other NG6 "3X" series valve (e.g., 4WREE6...-3X) without modifying the subplate.
Q: What is the purpose of the drain port (Y)?
A: The Y port serves two critical functions: 1) It drains internal leakage oil from the solenoid cavities to prevent pressure buildup. 2) It provides a reference pressure for the internal LVDT position sensor. This port must be connected directly to the tank (unpressurized). A blocked drain line can cause valve failure.
Q: Is an external amplifier card required?
A: No. The "4WREE" series features Integrated On-Board Electronics (OBE), which includes the amplifier and closed-loop spool position control. You connect the ±10V signal and 24V power directly to the valve's electrical connector. Do not use an external VT-VSPA1 amplifier with this valve.
