SPARKLING Doosan Throttle Controller – Precision Excavator Control

The Throttle Controller (part no. 543‑00074 / 2543‑1036) is a high-quality electronic throttle module engineered specifically for Doosan Daewoo excavators—most notably the SOLAR 130LC-V, 150LC-V, 200W-V, 220LC-V, and related models. This plug‑and‑play controller ensures precise engine acceleration, smooth operation, and reliable performance under heavy load. With OEM-level craftsmanship or dependable aftermarket alternatives, it’s tested for durability and fast shipping globally.

   SPARKLING MACHINERY NEW PC490 708-1T-13450/708-1T-13620 Plate, Valve is a dedicated, high-precision hydraulic sealing component exclusively engineered for KOMATSU PC490 crawler excavators—heavy-duty equipment widely used in large-scale mining, construction, and quarrying projects. As a core sealing and pressure-regulating part of the excavator’s hydraulic valve assembly, it ensures tight sealing between valve components and assists in maintaining stable hydraulic pressure, preventing oil leakage and pressure loss during high-intensity tasks like rock breaking, bulk ore loading, and deep excavation. This function is vital for preserving hydraulic system efficiency, avoiding component damage from contamination, and reducing unplanned downtime that disrupts critical project workflows.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and compatible with part numbers 708-1T-13450 and 708-1T-13620, the Valve Plate withstands harsh working conditions: high hydraulic pressure (up to 36 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil corrosion and mechanical wear, providing long-lasting sealing and pressure support for KOMATSU PC490 excavators. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for daily high-load tasks.

   SPARKLING MACHINERY NEW SK485-9 DX420 DX480 472-0209 Crankshaft is a dedicated power transmission core component for Weichai-powered excavators, including SK485-9, DX420, and DX480 models (widely used in heavy construction, mining, and large-scale earthmoving). As the "engine power converter", it converts the reciprocating motion of engine pistons into rotational motion—driving key excavator systems like hydraulic pumps and generators to ensure stable power output during high-intensity tasks such as rock breaking, deep digging, and heavy lifting.
   Meeting Weichai OEM standards (part no. 472-0209), it maintains precise rotational balance, endures -30°C to 150°C engine temperatures, resists wear and vibration, and ensures long-term structural stability. Strict testing guarantees seamless compatibility with the three Weichai-powered excavator models and reliable engine operation.

   SPARKLING MACHINERY NEW EC140C EC160C EC210C EC220C 60100000 Control Unit is a core electronic management component for 4 Volvo excavator models (construction/mining use). It coordinates engine, hydraulic, and electrical systems to ensure precise, stable equipment operation. 
   Meeting Volvo OEM standards (60100000), it resists -30°C to 85°C temps, electromagnetic interference, and vibration, guaranteeing seamless compatibility and long-term reliable performance.
