VOLVO EXCAVATOR PARTS MADE IN CHINA NEW EC180D EC210C EC210D EC220D EC235C EC235D 14535259 RELIEF VALVE SPARKLING MACHINERY
SPARKLING MACHINERY NEW EC180D EC210C EC210D EC220D EC235C EC235D 14535259 Relief Valve is a dedicated, high-pressure safety component exclusively engineered for VOLVO EC180D, EC210C, EC210D, EC220D, EC235C, and EC235D crawler excavators—versatile mid-to-heavy-duty equipment widely used in construction, mining, and infrastructure projects. As the core safety guard of the excavator’s hydraulic system, it precisely limits maximum hydraulic pressure, preventing overload damage to critical components (hydraulic pumps, cylinders, pipelines) during high-intensity tasks like trench digging, rock breaking, and bulk material loading. This function is vital for maintaining system stability, avoiding costly component failures, and ensuring uninterrupted operation of VOLVO excavators.
Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number 14535259, the Relief Valve withstands harsh working conditions: high operating pressure (up to 32 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil contamination and mechanical wear, providing long-lasting pressure regulation reliability for the six VOLVO excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load tasks.
