   SPARKLING MACHINERY NEW R200W2 4472.320.056 Hub is a premium China-made core component specifically engineered for R200W2 wheel excavators. As a critical part of the undercarriage system, it serves as the central connecting unit between the wheel, axle, and hydraulic components, ensuring stable load distribution and smooth rotational movement during machinery operation.

   Designed to original equipment standards, it maintains precise alignment and high load-bearing capacity, performing reliably even under heavy workloads and continuous vibration. With enhanced structural stability and wear-resistant properties, it adapts seamlessly to harsh working environments, from rough construction sites to muddy terrain. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW EC120D EC140B EC140C EC140D EC140E 14524582 Relief Valve is a dedicated hydraulic safety component for VOLVO EC120D, EC140B, EC140C, EC140D, and EC140E crawler excavators (mid-sized equipment for construction, municipal engineering, and light mining). As the core safety guard of the hydraulic system, it precisely limits maximum pressure to protect pumps, cylinders, and pipelines from overload damage during trench digging, material loading, and small-scale rock breaking.

   Meeting VOLVO OEM standards (part no. 14524582), it endures 30 MPa pressure, -25°C to 105°C temperature fluctuations, and continuous vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing seamless compatibility and safe operation.

   SPARKLING MACHINERY NEW 420F 428E 428F 430F 432E 432F 360-7435 Valve GP-Rel is a dedicated hydraulic relief valve group for Caterpillar 420F, 428E, 428F, 430F, 432E, and 432F backhoe loaders/excavators (widely used in construction, mining auxiliary, and municipal infrastructure projects). As a core safety component of the equipment’s hydraulic system, it regulates and limits maximum hydraulic pressure—preventing overpressure damage to pumps, cylinders, and valves during high-intensity tasks like heavy digging, material loading, and backhoe operation.
   Meeting Caterpillar OEM standards (part no. 360-7435), it endures 32 MPa maximum pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains stable pressure relief performance. Strict testing guarantees seamless compatibility with the six Caterpillar models and long-term hydraulic system protection.
