Product Introduction:
The 860569320 is a solenoid valve body used in the hydraulic system of the XCMG XE370 series excavator. It is a control component that directs hydraulic fluid flow based on electrical signals from the machine's control system.
1. Installation Location
This valve body is installed within the excavator's main hydraulic control valve assembly, typically mounted on the upper structure near the main pumps. The XE370 series is equipped with a dual variable pump main hydraulic system operating at pressures up to 34.3 MPa (main system) and 37 MPa (power-max pressure). The solenoid valve body is positioned to regulate pilot or main oil flow for specific functions such as boom, arm, bucket, or swing control.
2. Function
The solenoid valve body controls the direction and flow of hydraulic oil by opening or closing internal passages when electrically energized. It receives control signals from the excavator's electronic control unit and adjusts the valve spool position to regulate the corresponding hydraulic actuator. This enables precise and responsive operation of the machine's working functions. The XE370's hydraulic system uses load-sensing control to match pump output to operating demand, ensuring efficient power delivery.
3. Maintenance and Service
Regular inspection includes checking the solenoid coil and electrical connector for damage, verifying the valve spool moves freely, and ensuring no external leakage at the ports. As a precision hydraulic component, the valve body is not user-serviceable internally. If a fault is confirmed, replacement with an identical 860569320 unit is recommended. Before removal, fully depressurize the hydraulic system and disconnect electrical power.
4. Important Notes
Always verify the part number 860569320 matches the original component specification for the specific XE370 model variant (e.g., XE370CA, XE370G, XE370D). Confirm the solenoid voltage rating matches the machine's electrical system before installation. After replacement, check all connections for leaks and test the corresponding hydraulic function before returning the excavator to full operation.
