Replacement & Compatibility FAQ
Q: Can I replace a 4WRPEH6 C3 B04L-2X with a 3X generation model?
A: Yes. The 3X generation is the current production version and is a direct functional replacement. Wiring and mounting are identical; only the internal electronics revision differs.
Q: Does this valve require an external amplifier card?
A: No. The F1M suffix indicates integrated OBE (on-board electronics). A ±10 V or 4–20 mA command signal from your PLC analog output is sufficient.
Q: What is the enable input (F1M) and how is it wired?
A: The enable input is a digital 24 VDC signal that activates the valve electronics. When the enable is LOW, the valve defaults to the spring-centered (safe) position regardless of the command signal.
Q: Can the 4WRE6 series replace this valve?
A: The 4WRE6 uses the same NG6 mounting but requires an external amplifier card (e.g., VT-VSPA2). It is a viable replacement if an amplifier is already present in the system.
Q: Is this valve compatible with water-glycol (HF-C) hydraulic fluid?
A: Consult Rexroth datasheet RE 29 054. Special seal kits are required for HF-C/HF-D fluids. Contact Konmask for the correct variant.
Q: What is the lead time for out-of-stock units?
A: Standard lead time from Rexroth factory or authorized distribution is 4–8 weeks. Konmask maintains buffer stock for fast-moving variants — contact us for current availability.
