Q: What is the difference between R901496441 (/24F1) and R901496432 (/24A1)?
A: The control signal. R901496441 (/24F1) requires a 4–20 mA current signal, while R901496432 (/24A1) requires a ±10 V voltage signal. Mechanically, they are identical and share the same NG6 mounting interface.
Q: Can I use this valve with a ±10V PLC output?
A: No. The /24F1 suffix mandates a 4–20 mA current input. If your controller outputs ±10V, you must use the /24A1 version or add a signal converter.
Q: What does "W1" spool mean?
A: W1 indicates a specific variant of the overlap spool with a particular flow characteristic. Functionally, it behaves similarly to the standard W spool (providing smooth metering at low flows), but it is part of the newer 3X series with updated specifications.
Q: Is an external amplifier required?
A: No. This valve features Integrated On-Board Electronics (OBE), which includes the amplifier and closed-loop spool position control. You connect the 24V power and 4–20 mA signal directly to the valve's electrical connector.
Q: What is the critical installation note for the drain port?
A: The Y port (drain) must be connected directly to the tank without any pressure. It drains internal leakage and provides a reference for the LVDT sensor. A blocked or pressurized drain line will cause erratic valve behavior and potential failure.
Q: Is the mounting compatible with other NG6 valves?
A: Yes. The "3X" designation confirms it uses the standard ISO 4401-03-02-0-05 interface. It is directly interchangeable with other NG6 "3X" series valves without modifying the subplate.
