Q: What is the difference between 4WRZ and 4WRZE series?
A: The 4WRZ series typically features integrated on-board electronics (OBE) and a wider range of configurable spool options (like the W6 overlap spool in this valve). The 4WRZE series you inquired about earlier often uses external or simpler electronics. The 4WRZ is generally more modern and feature-rich.
Q: What does the /D3V suffix mean?
A: The /D3 suffix indicates an integrated pressure reducing valve (ZDR 6) for regulating pilot pressure. The /V suffix specifies FKM (Viton®) seals, which are suitable for higher temperatures (up to 80°C) and aggressive hydraulic fluids (e.g., certain biodegradable oils or oils with additives) compared to standard NBR seals (/M).
Q: Does this valve have LVDT feedback?
A: No. This standard 4WRZ model with a W6 spool does not have LVDT feedback for the main spool position. It operates in open-loop for the main stage. For closed-loop control, you would need a model with an "E" or "E1" spool designation.
Q: What is the purpose of the W6-spool?
A: The W6-spool is an overlap spool designed for applications requiring smooth acceleration and deceleration (e.g., crane or winch control). It has a progressive flow characteristic that reduces shock at the start of movement.
Q: What is the critical installation note?
A: This valve requires external pilot oil supply (X port) and external drain (Y port). You must connect the Y port directly to the tank with minimal backpressure (max 30 bar). The main T-port backpressure must be below 210 bar. Maintain high oil cleanliness (recommended NAS 1638 Class 8 or better for the main stage).
