152D-423A-1 is a high-performance hydraulic electromagnetic directional valve. It is mainly used for automatic direction switching of hydraulic circuits in construction machinery, industrial automation equipment and mobile hydraulic systems. It features sensitive action, stable performance and reliable reset function, which can precisely control the movement direction of hydraulic actuators.

Working medium: Industrial mineral hydraulic oilFluid cleanliness: Conform to ISO 4406 standardRated working pressure: 21 MPaMax allowable impact pressure: 25 MPaApplicable oil viscosity: 15 ~ 68 mm²/sOperating temperature range: -20℃ ~ +80℃Control power supply: Standard DC voltageSwitching response: Fast and accurate reversingLeakage performance: Ultra low internal and external leakageInstallation form: Standard thread connectionWorking feature: Suitable for frequent continuous switching

Adopts precision matching valve core, flexible movement without sticking or blocking. High-quality electromagnetic coil ensures stable operation, low heat generation and long service life. Optimized inner flow channel effectively reduces flow resistance and energy loss. High-strength wear-resistant parts improve overall durability. Multi-group sealing structure provides excellent leak-proof effect. Strong anti-vibration performance adapts to various harsh working conditions. Compact overall structure, easy installation, simple wiring and convenient field maintenance.

Clean oil ports and internal pipelines thoroughly to remove dirt and impurities before installation. Install the valve correctly and fasten threads with standard torque, avoid over tightening to prevent damage. Connect hydraulic pipelines strictly follow the oil flow direction. Cut off power supply before wiring, connect control wires according to specifications and fix wiring harness steadily. Recheck all assembly connections to ensure firm installation.

Finish installation and perform no-load test firstly. Fill hydraulic oil slowly and inspect all joints for oil leakage. Start formal operation after confirming no abnormal conditions. The valve realizes rapid circuit reversing when energized, and returns to original position steadily after power off. Keep hydraulic oil clean and replace filter elements regularly in daily use. Overpressure and overvoltage operation are strictly prohibited. Release all system pressure completely before maintenance and long-term shutdown.

Regularly check threaded joints and valve body for oil seepage, replace damaged seals timely. Periodically inspect coil operating condition and circuit connection stability. Keep the outer surface clean to guarantee normal heat dissipation. Unauthorized disassembly is forbidden to avoid damage to internal precision components.

All installation, wiring and maintenance work must be done after power cut and full hydraulic pressure relief, to prevent electric shock and high-pressure fluid injury. Operate in strict accordance with safety operating rules. Keep the valve away from high temperature sources and corrosive substances. Stop using immediately once abnormal heating, strange noise and slow reversing appear, and arrange professional inspection and repair in time.
