This is a high-quality hydraulic pressure control valve, applied in medium and high pressure hydraulic systems. It is widely used for engineering machinery, lifting equipment and industrial hydraulic stations, realizing system pressure limiting, overload protection and pressure stabilization to safeguard normal operation of hydraulic components.

Working medium: Mineral hydraulic oilFluid cleanliness: ISO 4406 standardRated working pressure: 21 MPaMax peak pressure: 26 MPaApplicable oil viscosity: 15~68 mm²/sWorking temperature: -20℃ ~ +80℃Control type: Mechanical adjustable typeInternal leakage: Ultra low leakageConnection type: Standard thread connectionWorking performance: Stable for long-term heavy load operation

High strength valve body with outstanding pressure resistance and durability.Precision fitted internal parts ensure flexible movement and stable control.Streamlined flow channel reduces flow loss and improves system efficiency.Excellent combined sealing structure prevents internal and external oil leakage effectively.Good vibration and impact resistance, adaptable to harsh working conditions.Standard universal structure, easy installation, debugging and replacement.Low failure rate, simple structure and convenient daily maintenance.

Clean oil ports and internal pipelines thoroughly to remove impurities before installation.Fasten the valve with standard torque, avoid excessive tightening to prevent thread damage.Connect pipelines strictly follow the specified oil flow direction.Recheck all connecting parts to ensure firm assembly and good sealing after installation.

Perform low-pressure no-load test after installation and check all positions for leakage.Adjust working pressure reasonably according to actual working demands.Keep hydraulic oil clean and replace filter elements regularly to avoid blockage.Strictly prohibit over-pressure operation beyond the rated range.Fully release system pressure before equipment maintenance and shutdown.

Regularly check sealing parts and threaded joints for oil seepage, replace damaged accessories timely.Regularly verify pressure control accuracy and make fine adjustment if needed.Keep valve outer surface clean to ensure good heat dissipation.It is forbidden to disassemble privately so as not to damage internal precision parts.

All installation, adjustment and maintenance must be done after equipment stop, power off and full hydraulic pressure relief to avoid high-pressure fluid injury.Operate in compliance with safety operation regulations.Keep away from high temperature sources and corrosive substances.Stop using immediately once abnormal noise, pressure instability and leakage occur, and arrange professional inspection and repair.
