   SPARKLING MACHINERY NEW EC55C EC60C EC60E ECR58D ECR88D 14576751 Solenoid Valve is a critical hydraulic control component for Volvo EC55C, EC60C, EC60E, ECR58D, and ECR88D excavators (widely used in small-scale construction, landscaping, and municipal maintenance). As the "hydraulic flow regulator", it precisely controls the on/off and direction of hydraulic oil for key functions like bucket tilting, arm lifting, and auxiliary tool operation—ensuring responsive and smooth performance during light-duty tasks, while preventing oil leaks or pressure mismatches that reduce equipment efficiency.
   Meeting Volvo OEM standards (part no. 14576751), it withstands -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees stable electromagnetic switching. Strict testing ensures seamless compatibility with the five Volvo models and long-term reliability of the hydraulic system.

   SPARKLING MACHINERY NEW SD300 130113-00035 Plate, Friction is a dedicated transmission system component for DOOSAN SD300 crawler excavators (heavy-duty equipment for mining, large-scale construction, and bulk material handling). As a key part of the excavator’s clutch or brake mechanism, it generates stable friction force to control power transmission and braking during tasks like heavy ore loading, rock breaking, and slope excavation—ensuring smooth speed adjustment and safe stopping.
   Meeting DOOSAN OEM standards (part no. 130113-00035), it endures high friction temperatures (up to 280°C), resists wear and oil contamination, and maintains consistent friction coefficient. Strict performance testing guarantees seamless compatibility and long-term reliable operation for DOOSAN SD300.

   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.
