152D453 is a reliable hydraulic solenoid directional valve. It is widely used in construction machinery, agricultural machinery, industrial automation and mobile hydraulic systems. It controls hydraulic oil flow direction to realize forward, reverse and stop actions of actuators, with stable operation and quick response.

Working medium: Mineral based hydraulic oilFluid cleanliness: ISO 4406 standardRated working pressure: 21 MPaMaximum impact pressure: 25 MPaApplicable oil viscosity: 15~68 mm²/sWorking temperature: -20℃ ~ +80℃Control voltage: Standard DC voltageAction feature: Fast reversing and stable resetLeakage: Low internal and external leakageInstallation: Standard thread mountingApplication: Frequent continuous switching operation

Precision machined spool ensures smooth movement without jamming. Durable electromagnetic coil runs steadily with low heat generation. Optimized flow passage reduces flow resistance and energy consumption. Excellent sealing design effectively prevents oil leakage. Good vibration resistance adapts to complex working sites. Compact structure saves installation space, easy to assemble and wire. Simple structure, low failure rate and easy maintenance.

Clean oil ports and internal oil passages to remove impurities before installation. Install the valve and tighten threads with proper torque, avoid over-tightening damage. Connect hydraulic pipes strictly in accordance with flow direction. Cut off power supply before wiring, connect lines as required and fix wire harness firmly. Confirm all connections are firm after installation.

Complete installation and conduct no-load test. Inject hydraulic oil slowly and check all connections for leakage. Put into formal use after no abnormality is confirmed. The valve completes oil circuit reversing quickly when energized, and resets reliably after power off. Keep hydraulic oil clean and replace filters regularly. Do not exceed rated pressure and voltage for use. Fully release system pressure before maintenance.

Check valve body and joints regularly for oil seepage, replace aging seals in time. Inspect coil working status and circuit connection periodically. Keep surface clean for good heat dissipation. Do not disassemble privately to avoid damage to internal precision parts.

All installation, wiring and maintenance shall be carried out after power off and full hydraulic pressure relief to avoid electric shock and high-pressure fluid injury. Follow safety operation rules strictly. Keep away from high temperature and corrosive materials. Stop operation immediately in case of overheating, abnormal noise and insensitive action, and arrange professional inspection and repair.
