Description
Parker D1FBE01HC0NF00 directional control valve
Parker D1FBE01HC0NF00 Product Introduction
The Parker D1FBE01HC0NF00 is a direct – operated proportional directional control valve, meticulously engineered to meet the stringent demands of industrial hydraulic systems. Its high – precision control, wide operational adaptability, and intelligent features make it a core component in various industrial applications, especially in machine tools, rubber, and tire processing.
1. Core Technical Specifications and Design Features
1.1 Interface and Installation Standardization
Port Connection: Adopting the NG06/CETOP 03 standard interface, it is compatible with mainstream hydraulic systems, enabling rapid integration into existing equipment.
Subplate Mounting: The subplate mounting method simplifies system layout, and its unrestricted mounting position allows for flexible adaptation to different spatial conditions.
Connection Type: The 6 + PE electrical interface (6 signal pins + 1 protective grounding pin) ensures reliable electrical connections and excellent anti – interference performance, meeting the harsh requirements of industrial environments.
1.2 Precision Control and Drive Mechanism
Direct – Operated Operation: Driven directly by a proportional solenoid, it offers fast response speed with optimized dynamic performance. Without the need for a complex pilot – stage oil circuit, it reduces energy consumption and leakage risks.
Spool Design: Featuring a precise Spool/sleeve structure, the hardened steel components are finely ground to achieve an ultra – low hysteresis of <4% and high repeatability accuracy. This makes it particularly suitable for closed – loop control systems that require precise regulation of micro – flow rates.
Signal Input: It supports a 0 – ±10V analog signal, seamlessly interfacing with control devices such as PLCs and industrial computers to achieve stepless adjustment of flow and direction.
1.3 Materials and Sealing Performance
Seal Material: NBR (Nitrile Butadiene Rubber) seals are resistant to mineral oils, hydraulic oils, and other media. They maintain stable elasticity within a temperature range of – 25°C to 60°C, effectively preventing leakage.
Body Material: The cast iron body provides a robust structure, capable of withstanding a maximum pressure of 350 bar, ensuring long – term load – bearing in high – pressure hydraulic systems.
2. Performance Advantages and Application Value
2.1 Adaptability to Extreme Working Conditions
Temperature Range: With an operating temperature range of – 25°C to 60°C and an ambient temperature range of – 20°C to 60°C, and a wide viscosity range (20 – 400 cSt), it can adapt to changes in hydraulic oil properties in cold regions or high – temperature environments.
Ingress Protection Rating: The IP65 dust – proof and waterproof design allows it to operate stably in dusty, humid, or mildly water – sprayed industrial environments, reducing maintenance frequency.
2.2 System Reliability Assurance
Filtration Compatibility: It supports the ISO 4406:18/16/13 cleanliness standard, tolerating a certain level of particulate contamination in the oil. When used with an external filter, it can extend the service life and reduce downtime risks.
Leakage Control: With a leakage rate of <50 mL/min at 350 bar pressure, it ensures the energy efficiency and stability of the hydraulic system, especially suitable for precision equipment sensitive to leakage.
2.3 Intelligence and Convenience
Onboard Digital Electronics: The built – in electronic module supports personalized parameter settings (such as flow curves and response speed). Full data access enables precise calibration, reducing on – site commissioning time.
Manual Override Function: Equipped with a mechanical emergency handle, it allows the spool to be manually driven to a safe position in case of power failure or malfunction, enhancing system redundancy.
3. Typical Application Scenarios
3.1 Industrial Automation Equipment
Hydraulic Axis Positioning: In machine tool feed systems, its <4% hysteresis and high – precision spool control achieve micron – level position repeatability, ensuring dimensional consistency of machined parts.
Pressure Regulation: In rubber and plastic machinery, proportional control enables precise adjustment of mold cavity pressure, optimizing product molding quality and reducing scrap rates.
3.2 Rubber and Tire Processing
Vulcanizer Control: During tire vulcanization, it adjusts the pressure and speed of hydraulic cylinders in real – time, ensuring precise matching of vulcanization temperature and time to improve tire uniformity.
Extruder Drive: It controls the speed and torque of hydraulic motors, achieving stable flow output during rubber extrusion and adapting to different formulation and process requirements.
3.3 General Machinery and Machine Tools
Injection Molding Machine Clamping: It provides high – pressure clamping force during the clamping stage. The low – hysteresis feature enables rapid response to pressure changes, preventing mold deformation or flash in products.
Press Synchronization Control: When multiple valves work in tandem, their high inter – valve repeatability ensures synchronized movement of multiple cylinders, improving the machining accuracy of large – scale presses.
4. Selection and Maintenance Recommendations
4.1 Selection Considerations
Select the appropriate model based on the system’s maximum pressure (≤350 bar) and flow requirements (20 L/min), and pay attention to the compatibility of the viscosity range with the hydraulic oil type.
For applications in explosive – hazardous environments, it is recommended to choose other Parker models with explosion – proof certification (such as the D1VW series), as this model has not passed explosion – proof testing.
4.2 Installation and Commissioning
Ensure a flat subplate surface during installation to avoid stress concentration affecting spool movement.
Use the supporting proportional amplifier (such as BEUEC US – DAS1) for parameter setting to optimize dynamic response characteristics.
4.3 Maintenance Tips
Regularly check the oil cleanliness. It is recommended to replace the filter element every 2000 operating hours to ensure the cleanliness meets the ISO 18/16/13 standard.
Inspect the aging condition of seals. NBR seals need to be replaced in a timely manner after long – term use in high – temperature environments to maintain sealing performance.
In summary, the Parker D1FBE01HC0NF00 offers an efficient and reliable solution for industrial hydraulic systems with its precise spool design, wide operational adaptability, and intelligent control capabilities. Whether it is the micron – level positioning of machine tools or the high – pressure molding in rubber processing, this valve can help users improve production efficiency and product quality through low hysteresis, high repeatability, and fast response. Its high cost – effectiveness, short delivery time, and convenient maintenance further enhance its competitiveness in the industrial field.
