This is a high-precision hydraulic control valve, widely used in construction machinery, lifting equipment and industrial hydraulic systems. It is applied for oil circuit switching, pressure limiting and hydraulic protection, with stable performance and strong environmental adaptability.

Working medium: Standard mineral hydraulic oilFluid cleanliness: ISO 4406 standardRated pressure: 21 MPaMax peak pressure: 25 MPaApplicable viscosity: 15-68 mm²/sOperating temperature: -20℃ ~ +80℃Response performance: Quick and flexible actionInternal leakage: Low flow leakageInstallation form: Standard cartridge installationWorking condition: Suitable for frequent continuous operation

Made of high strength alloy materials, wear resistant and pressure resistant. Optimized inner flow channel reduces flow loss and improves working efficiency. Compact structure saves installation space, easy to assemble and replace. Excellent sealing structure effectively avoids oil seepage. Good shock resistance, stable operation under complex working conditions. Simple internal structure, low failure rate and easy maintenance.

Clean all oil passages and mounting holes before installation to remove impurities. Install the valve in correct position and fasten according to specified torque, avoid over tightening. Connect pipelines strictly following oil inlet and outlet direction. Check assembly tightness and pipeline connection after installation completion.

Carry out no-load test firstly after installation, check all positions for oil leakage. Start formal operation after confirming normal condition. Keep hydraulic oil clean and replace filter regularly. It is forbidden to run beyond rated pressure and temperature range. Release system pressure completely before stopping equipment maintenance.

Regularly check external leakage and replace worn sealing parts timely. Inspect operating condition regularly to ensure sensitive action. Keep valve surface clean to prevent dirt accumulation. Do not disassemble privately to avoid damage to internal precision parts.

All installation and maintenance must be performed after power off and full pressure relief of hydraulic system to prevent high-pressure liquid injury. Please operate in accordance with safety regulations. Keep away from high temperature and corrosive substances. Stop using immediately once abnormal noise and overheating occur, and carry out inspection and repair in time.
