D91FBB32HC1NS00 Parker // Parker Proportional Valve

  • About the Flow (Code 32): In the Parker D91FB series, the number 32 indicates the NG32 size, which corresponds to a very high flow capacity of approximately 700 L/min (at Δp = 10 bar). This valve is designed for large-scale industrial applications such as injection molding machines, presses, and heavy-duty test rigs.
  • About the Spool (Code B): The B spool type typically features a specific mid-position function. You should consult the Parker D91FB series catalog to confirm the exact spool configuration for your application.
  • About the Seals (Code N): This valve uses NBR (Nitrile) seals, which are suitable for standard mineral-based hydraulic oils. If your system uses fire-resistant fluids or operates at high temperatures, you may need a valve with FKM (Viton) seals.
  • About the Custom Code (0014): The 0014 suffix indicates a factory-specific modification. This could involve special tuning of the PID parameters, specific ramp times, or unique flow characteristics tailored to a particular machine or application.
    • Replacement Advice: Do not replace it with a standard D91FB valve without the 0014 suffix. The internal digital electronics and tuning parameters may not match your system, potentially causing instability, poor performance, or machine faults.
For the absolute most accurate data, always refer to the metal nameplate on the valve body or contact Parker Hannifin support with the valve’s Serial Number to retrieve the original factory test sheet and configuration data.
