   SPARKLING MACHINERY's new 11LD-20240 Head Filter is a core filtration component specifically designed for Hyundai 100D-7/50DE/50DEACE/50DF/50DS-7E/80D-7 excavators, suitable for construction and mining applications. It filters impurities such as dust, metal particles, and sludge from the hydraulic or fuel system, protecting key components from abrasion. 
   Compliant with Hyundai OEM standards (Part No.: 11LD-20240), this component exhibits excellent filtration efficiency and structural stability, ensuring seamless compatibility with original equipment and long-term reliable operational performance.

   SPARKLING MACHINERY NEW 420E 422F 428F 430E 432F 348-9761 Valve GP-P R is a dedicated hydraulic pressure reducing valve group for Caterpillar 420E, 422F, 428F, 430E, and 432F backhoe loaders/excavators (widely used in construction, municipal engineering, and heavy material handling). As a core pressure control component, it reduces high-pressure oil from the main hydraulic system to a stable, safe level for sensitive sub-systems (e.g., hydraulic steering, auxiliary controls)—ensuring smooth, damage-free operation during tasks like heavy digging, loading, and backhoe maneuvering.
   Meeting Caterpillar OEM standards (part no. 348-9761), it endures 28 MPa inlet pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains consistent pressure reduction. Strict testing guarantees seamless compatibility with the five models and long-term hydraulic sub-system protection.

   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.
