Hydraulic Return Line Filter, GY-GLQ-40

The hydraulic return-line filter removes metal particles, seal debris, dust, and other solid contaminants before hydraulic oil returns to the reservoir. By maintaining fluid cleanliness, the filter helps protect hydraulic pumps, control valves, and cylinders from wear and blockage, supporting a longer service life for the hydraulic system.

    Features
    • Broad filtration range: The standard return line filter options cover 160–500 mesh (100–550 μm), with custom 1–30 μm multistage fine filtration available for applications requiring finer contaminant control.
    • Low flow resistance: The filter element removes particles through physical interception while maintaining low flow resistance, limiting pressure loss at flow rates from 150 to 610 L/min.
    • Bypass protection: A standard bypass valve opens automatically when the filter element becomes clogged, and differential pressure reaches the set point, allowing the hydraulic system to continue operating.
    • Optional clogging indicator: An optional indicator alerts maintenance personnel when the filter element requires replacement, helping prevent faults caused by ineffective filtration.
    • Multiple connection sizes: Connection size options from 25 to 80 mm are available to cover the flow requirements of systems ranging from small hydraulic power units to large construction machinery.
