SPARKLING EC300D Hydraulic Valve

The Volvo Swing Motor Valve Assembly (VOE 14558299 / 14558299 / 14775509 / 14672659) is a high‑precision relief/control valve engineered for the swing motor circuit in medium-to-large Volvo excavators—ranging from EC200B, EC235D, ECR235D to EC300D models. This valve regulates hydraulic pressure and protects the swing motor from overload, ensuring smooth 360° rotation and safe operation. Manufactured to OEM standards, it offers both genuine and premium aftermarket options that fit directly and restore reliable machine performance.

   SPARKLING MACHINERY NEW RA211-42300 Radiator is a critical cooling system component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s heat dissipation system, it efficiently transfers heat from engine coolant to the surrounding air—preventing engine overheating during high-intensity operations like prolonged digging, heavy-load lifting, and continuous idling in construction, mining, or infrastructure projects. This function is vital for maintaining the engine’s optimal operating temperature (typically 82–95°C), which directly influences fuel efficiency, power output, and the long-term service life of key engine components.

   Engineered to match original equipment performance standards, it retains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and constant machinery vibration. It resists coolant leakage and internal blockages, avoiding cooling system failures that could lead to costly engine damage or unplanned downtime. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW ME990328/60289472 Water Pump is a critical cooling system component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core power source of the machinery’s coolant circulation system, it drives engine coolant to flow through radiators, engine blocks, and other heat-generating components—effectively transferring excess heat and maintaining the engine’s optimal operating temperature (typically 82–95°C). This function is vital for preventing engine overheating during high-intensity operations like prolonged digging, heavy-load lifting, and continuous idling in construction, mining, or infrastructure projects, directly safeguarding engine power output, fuel efficiency, and long-term service life.

   Engineered to match original equipment performance standards, it maintains stable coolant flow rate and pressure even under harsh working conditions, including high ambient temperatures, continuous machinery vibration, and exposure to dust or coolant contaminants. It resists leakage, bearing wear, and impeller damage, avoiding cooling system failures that could lead to costly engine repairs or unplanned downtime. Backed by strict performance verification, it guarantees reliable circulation performance to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW CX460 CX470B CX470C LJ00981 Main Relief Valve is a dedicated, high-pressure hydraulic safety component exclusively engineered for CASE CX460, CX470B, and CX470C crawler excavators—heavy-duty equipment widely used in large-scale construction, mining, and quarrying projects. As the core safety guard of the excavator’s hydraulic system, it precisely controls and limits maximum hydraulic pressure (preventing exceeding safe thresholds), protecting critical components like hydraulic pumps, cylinders, and pipelines from damage caused by pressure spikes. This function is vital for maintaining stable hydraulic performance during high-intensity tasks (e.g., rock breaking, bulk ore loading) and avoiding costly downtime from hydraulic system failures.

   Engineered to meet CASE’s original equipment (OEM) standards and marked with the genuine part number LJ00981, the main relief valve withstands harsh working conditions: high operating pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil contamination and mechanical wear, ensuring long-lasting pressure regulation reliability for the three CASE excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load tasks.
