D41FCE01FC4NB70 Parker // Parker, Proportional Valve
- About the Flow (Code F): In the Parker D41FC series, the letter
Findicates a specific flow rating. Based on the NG16 size and pilot-operated design, this valve has a maximum flow capacity of approximately 100 L/min at Δp = 5 bar per metering edge. This makes it suitable for medium industrial applications such as presses, injection molding machines, and machine tools. - About the Spool (Code E01): The
E01spool code provides progressive flow characteristics with a 0-type mid-position (all ports closed when de-energized). This allows for sensitive and gradual flow adjustment, ideal for applications requiring smooth acceleration and deceleration of actuators. - About the Pilot Connection (Code 4): The
4in the part number indicates internal pilot oil 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. If your system uses fire-resistant fluids or operates at high temperatures, you would need a valve with FKM (Viton) seals.
- 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 D41FC 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 D41FC valve without the
