D91FCB32HC2NE70 Parker // Parker Proportional Valve
- About the Flow (Code 32): In the Parker D91FC series, the number
32indicates the NG32 size, which corresponds to a very high flow capacity of approximately 1100 L/min (at Δp = 10 bar). This valve is designed for extremely large-scale industrial applications such as heavy presses, large injection molding machines, steel mill equipment, and marine hydraulic systems. - About the Spool (Code B): The
Bspool type typically features a specific mid-position function. You should consult the Parker D91FC series catalog to confirm the exact spool configuration for your application. - About the Seals (Code E): This valve uses FKM (Viton) seals, which are excellent for high-temperature environments or systems using fire-resistant fluids such as water-glycol and phosphate esters. This is a significant advantage if your system operates at elevated temperatures or uses special hydraulic fluids.
- About the Custom Code (7019): The
7019suffix 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 D91FC valve without the
7019suffix. The internal digital electronics and tuning parameters may not match your system, potentially causing instability, poor performance, or machine faults.
- Replacement Advice: Do not replace it with a standard D91FC valve without the
