VOLVO EXCAVATOR PARTS MADE IN CHINA NEW EC330B EC330C EC340D EC360B EC380D VOE114577744 RELIEF VALVE SPARKLING MACHINERY
SPARKLING MACHINERY NEW EC330B EC330C EC340D EC360B EC380D VOE114577744 Relief Valve is a dedicated, high-precision hydraulic component exclusively engineered for VOLVO EC330B, EC330C, EC340D, EC360B, and EC380D crawler excavators—heavy-duty equipment critical for large-scale mining, construction, and infrastructure projects. As a core safety and pressure-regulating part of the excavator’s hydraulic system, it monitors hydraulic pressure in real time and automatically releases excess pressure to prevent overloading of key components like hydraulic pumps, cylinders, and valves. This function is vital for maintaining stable hydraulic operation during high-intensity tasks such as rock breaking, bulk ore loading, and deep excavation, avoiding pressure-surge damage and ensuring uninterrupted workflow.
Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE114577744, the relief valve withstands harsh conditions: high hydraulic pressure (up to 42 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous heavy-duty vibration. It maintains precise pressure regulation accuracy and resists oil contamination, providing long-lasting reliability for the excavators’ hydraulic systems. Backed by strict performance verification, it guarantees seamless compatibility and operational safety for EC330B/EC330C/EC340D/EC360B/EC380D models.
