Sany SY500C High Quality Excavator Hydraulic Main Control Valve KMX32NA with 6-Month Warranty
Product Overview
The Volvo EW180B main control valve is the core control component of the excavator's hydraulic system, responsible for regulating the flow, pressure, and volume of hydraulic oil to achieve precise control of various excavator movements.
Function and Structure
The main control valve typically contains multiple spool valves, such as those for the boom, arm, bucket, and travel control valves. Changing the position of these spool valves via a control lever drives the corresponding actuators. For example:
- Boom control valve adjusts the boom's raising, lowering, holding, and regenerating functions
- Arm control valve controls the arm's extension and retraction
Technical Specifications
- Pressure Rating: Generally supports high-pressure operation up to 350 bar (approximately 5000 psi), meeting heavy-duty requirements
- Flow Rate Adjustment Range: Automatically adjusts flow rate according to load changes, improving system efficiency
- Control Mode: May integrate load-sensitive control technology, dynamically distributing hydraulic power according to the actual needs of the actuators
Maintenance Points
- Hydraulic Oil Cleanliness: Requires ISO VG46 anti-wear hydraulic oil with a cleanliness level of NAS 7. Replace the filter element regularly
- Inspection Items: Regularly check valve body wear, seal aging, and the flexibility of the spool valve and the accuracy of the pressure setting
- Installation Requirements: During installation, ensure the valve body is securely connected to the oil pipe to prevent leakage, and pay attention to shaft alignment accuracy
If you encounter a hydraulic pump failure, it is recommended to contact local professional technicians for inspection, or reach out to us online for troubleshooting assistance, consultation, and supply of pump parts or complete assemblies. Avoid attempting improper repairs on your own, as this may lead to more severe damage or potential safety risks.
