PLFA High-Precision Pressure Line Filter

PLFA High-Precision Pressure Line Filter

The PLFA High-Precision Pressure Line Filter is installed in hydraulic pressure lines to remove mechanical impurities, colloids, carbon residues, and other oil contaminants. It helps reduce valve sticking, small-orifice blockage, and premature wear of hydraulic components. For pressure circuits requiring controlled cleanliness, it provides a practical Precision Hydraulic Line Filter solution.



Customised Services

The PLFA High-Precision Pressure Line Filter can be configured according to hydraulic circuit and equipment requirements.
Filtration Configuration: Match the glass-fiber element to the required cleanliness level.
Installation Adaptation: Coordinate connections and mounting with the pressure-line layout.
Signal Integration: Connect the 0.5 MPa differential pressure signal to the monitoring system.
Bypass Configuration: Match bypass protection with the circuit's operating requirements.
System Integration: A High Pressure Line Filter can be adapted to available installation space and protected component locations.

  • Areas of Application

    The PLFA Pressure Line Filter is suitable for hydraulic systems requiring controlled pressure-line cleanliness.
    Hydraulic Control Systems: Helps protect valves, throttling passages, and damping orifices from contamination.
    Industrial Machinery: Used in machine tools, hydraulic power units, automation equipment, and production machinery.
    High-Pressure Circuits: A high-pressure line filter helps reduce contamination before oil reaches sensitive components.
    Mobile Hydraulic Equipment: Supports cleaner oil in construction, lifting, and material-handling machinery.
    OEM Hydraulic Assemblies: Suitable for equipment manufacturers and system integrators requiring pressure-line filtration.
    Precision Hydraulic Equipment: The Precision Hydraulic Line Filter supports circuits with tighter cleanliness requirements.

  • Product Benefits

    High Filtration Efficiency: Glass-fiber media achieves ≥99.5% filtration efficiency for particulate control.
    Defined Filtration Ratio: β3, 5, 10, 20 ≥ 200 provides absolute filtration performance across multiple particle sizes.
    High Flow Capability: Glass-fiber media combines high oil-flow capacity with low initial pressure loss.
    High Dirt-Holding Capacity: The filter media supports longer operating periods before element replacement.
    Clogging Detection: The differential pressure signal activates at 0.5 MPa for timely element replacement.
    Bypass Protection: The integrated bypass valve helps maintain oil circulation when the element becomes excessively contaminated.

  • FAQ

    1. Which hydraulic components can this filter protect?
    It can help protect valves, throttling passages, damping orifices, and other sensitive hydraulic components from contamination.

    2. When should the filter element be replaced?
    The differential pressure signal activates at 0.5 MPa, providing a reference for checking and replacing the element.

    3. What filtration performance does the element provide?
    The glass-fiber element provides ≥99.5% filtration efficiency and β3, 5, 10, 20 ≥ 200 absolute filtration performance.

    4. Can it be integrated into OEM hydraulic equipment?
    Yes. A Precision Hydraulic Line Filter can be adapted to the circuit structure, connection arrangement, and protected components.

    5. What information is needed for purchasing?
    Provide the circuit arrangement, filtration requirements, installation conditions, connection specifications, and monitoring requirements when selecting a High Pressure Line Filter.
