Parker D41FB Series Pilot-Operated Proportional Valves

Product Overview:

The Parker D41FB series represents the industry standard in high-performance pilot-operated proportional control technology. Designed specifically for hydraulic systems requiring high flow rates and precise dynamic control, this series complies with the NG16 (CETOP 07) mounting interface. Featuring Integrated Electronics (OBE) and an advanced pilot stage, the D41FB provides exceptionally smooth flow regulation and shifting characteristics under high-pressure conditions. Its modular design makes it a preferred choice for injection molding, metal forming, and large-scale industrial automation.

Featured models: D41FBE01FC1NF00, D41FBE02FC4NF00, D41FBE02FC4NG00, and D41FBB32FC1NKW0.

Key Technical Advantages:

• Pilot-Operated High Dynamics: Optimized pilot stages ensure high shifting frequency and response accuracy even when handling massive flow rates.

• On-Board Electronics (OBE): The control circuitry is integrated directly onto the valve, factory-calibrated for precision, reduced wiring, and enhanced EMI resistance.

• Progressive Flow Characteristics: Specialized spool geometries ensure excellent fine-metering performance at low flow openings.

• Rugged Industrial Design: Constructed with high-strength cast iron and precision-machined internals to maintain low internal leakage at operating pressures up to 350 bar.

• Flexible Control Signals: Compatible with multiple standard analog inputs (e.g., $\pm10\text{V}$ or $4-20\text{mA}$) for seamless integration with various controllers.
