D111FBE01LC4NF00 Parker Proportional Valve
- About the Flow (Code L): In the Parker D111FB series, the letter
Lindicates a flow rating of 1000 L/min (at Δp = 5 bar per metering edge). This valve is designed for extremely large industrial applications such as heavy presses, large injection molding machines, steel mill equipment, and marine hydraulic systems. - About the Spool (Code E01): The
E01spool code provides specific progressive flow characteristics, allowing for sensitive and gradual flow adjustment. This is ideal for applications requiring smooth acceleration and deceleration of large actuators. - About the Pilot Connection (Code 4): The
4in the part number indicates internal pilot supply and internal drain. This means both the pilot oil supply and the pilot drain return to the tank internally through the main valve body. This configuration is used when the tank line backpressure is low and stable. - About the Seals (Code N): This valve uses NBR (Nitrile) seals, which are suitable for standard mineral-based hydraulic oils and water glycol fluids. If your system uses phosphate ester fluids or operates at very high temperatures, you would need a valve with FKM (Viton) seals.
- About the Custom Code (0014): The
0014suffix 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 D111FB valve without the
0014suffix. 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 D111FB valve without the
