Q: What is the difference between "W1" and standard "W" spools?
A: The W1 spool is a specific variant of the overlap spool family. It is designed for applications requiring smooth acceleration and deceleration with a particular flow curve. It typically has a slightly different mid-position characteristic compared to the standard W spool.
Q: Why choose the /F1 version over /A1?
A: The /F1 suffix indicates a 4–20 mA current input, which is more resistant to electrical noise over long cable runs compared to the /A1 version (±10V voltage input). This makes it suitable for industrial environments with significant EMI.
Q: Does this valve require an external amplifier?
A: No. The "E" in 4WREE and the /G24K31 suffix confirm Integrated On-Board Electronics (OBE). It operates directly with a 24V DC power supply and the 4–20 mA command signal.
Q: What is the advantage of the LVDT feedback?
A: The LVDT (Linear Variable Differential Transformer) provides internal closed-loop control of the spool position, ensuring high repeatability, accuracy, and insensitivity to oil contamination compared to open-loop valves.
Q: What is the critical installation note?
A: Maintain the T-port backpressure below 210 bar. Due to the precision spool and LVDT, ensure high oil cleanliness (recommended NAS 1638 Class 8 or better) to prevent damage to the tight tolerances.
