This product is a high performance hydraulic solenoid valve. It is widely used in engineering machinery, industrial hydraulic equipment and automatic control systems to realize automatic switch and direction control of hydraulic oil circuit. It features reliable action, compact structure and stable operation, which can meet the automatic control demands of various hydraulic equipment.

Working medium: Mineral based hydraulic oilFluid cleanliness: Meet ISO 4406 standardRated working pressure: 21MPaMax working pressure: 25MPaApplicable oil viscosity: 15-68 mm²/sAmbient working temperature: -20℃ ~ +80℃Control power: Standard DC power supplyAction response: Fast switching responseSealing performance: Low internal and external leakageInstallation method: Standard thread mountingWorking mode: Frequent continuous switching operation

Adopt precise spool matching structure with flexible switching and no jamming phenomenon. The coil has stable performance, low heat generation and long service life. Optimized internal flow channel reduces flow resistance and improves working efficiency. High quality sealing components are equipped to effectively prevent oil leakage. Good vibration resistance and environmental adaptability, suitable for various harsh working sites. Small overall size, easy installation and convenient wiring operation. Simple overall structure, low failure rate and easy daily maintenance.

Clean the connecting ports and internal oil passages before installation to remove impurities and oil dirt. Install the valve body at the designated position and tighten the thread according to standard torque, avoid excessive force damage. Connect hydraulic pipelines correctly following the oil flow direction. Cut off the power supply first when connecting electric wires, connect lines in accordance with wiring specifications and fix the wire harness firmly. Check all assembly and wiring conditions again after installation completion.

After all installation work is finished, perform no-load test operation. Slowly inject hydraulic oil and check all joints for oil leakage. Confirm no abnormality before formal power-on operation. The valve completes oil circuit switching rapidly after being energized, and resets quickly after power off. Keep the hydraulic oil clean during daily use, replace filter elements regularly to avoid internal blockage. It is forbidden to use beyond rated pressure and rated voltage range. Release system pressure completely before equipment maintenance.

Regularly check the valve body for oil seepage, replace aging sealing parts in time. Periodically check the working state of electromagnetic coil and connecting circuit to ensure stable power supply. Keep the product surface clean to prevent dust and oil dirt from affecting heat dissipation. It is not allowed to disassemble the valve privately without professional permission, so as not to damage internal precision parts.

All installation, wiring and maintenance operations must be carried out after power off and full pressure relief of hydraulic system to avoid electric shock and high-pressure oil injury. Operators shall abide by safety operation regulations. Keep the product away from high temperature heat sources and corrosive substances. Stop using immediately once abnormal heating, abnormal noise and insensitive action occur during operation, and arrange professional inspection and maintenance in time.
