   SPARKLING MACHINERY NEW EC120D EC135B EC140B EC140C EC140D 14509331 Expansion Valve is a dedicated thermal control component for VOLVO EC120D, EC135B, EC140B, EC140C, and EC140D crawler excavators (mid-sized equipment for construction, municipal engineering, and landscaping). As a key part of the excavator’s air conditioning system, it precisely regulates refrigerant flow to maintain stable cabin temperature, ensuring operator comfort during long-hour tasks in hot or cold environments.

   Meeting VOLVO OEM standards (part no. 14509331), it endures -30°C to 80°C temperature fluctuations, resists refrigerant corrosion and mechanical wear, and ensures consistent thermal control for the five VOLVO models. Strict performance testing guarantees seamless compatibility and reliable operation.

   SPARKLING MACHINERY NEW 463 553 553F 553AF 6678820 Radiator is a dedicated cooling component for Bobcat 463, 553, 553F, and 553AF mini excavators (versatile for landscaping, indoor demolition, and small-scale construction). As the core of the excavator’s cooling system, it dissipates heat from the engine and hydraulic oil to prevent overheating, ensuring stable performance during tasks like trench digging, material loading, and precision grading.
   Meeting Bobcat OEM standards (part no. 6678820), it endures -30°C to 110°C temperature fluctuations, resists dust and corrosion, and maintains efficient heat exchange. Strict testing guarantees seamless compatibility and long-term reliable cooling for the four Bobcat models.

   SPARKLING MACHINERY NEW 320D 323D 324D 325D 329D 330D 3E-8621 Coil is a dedicated electrical control component for CATERPILLAR 320D, 323D, 324D, 325D, 329D, and 330D crawler excavators (heavy-duty equipment for construction, mining, and infrastructure projects). As a key part of the excavator’s hydraulic or ignition system, it generates electromagnetic force to control valve actuation or ignition timing, ensuring stable operation of functions like boom movement and engine start during high-intensity tasks.
   Meeting CATERPILLAR OEM standards (part no. 3E-8621), it endures -30°C to 90°C temperatures, resists vibration and electrical interference, and maintains consistent electromagnetic performance. Strict testing guarantees seamless compatibility and long-term reliability for the six CATERPILLAR models.
