SPARKLING 709-63-11501 Control Valve – Reliable Excavator Part

The 709-63-11501 / 709-63-11600 Control Valve Assembly is a precision-engineered hydraulic component specifically designed for Komatsu D375A series bulldozers. As a key part of the machine’s hydraulic system, this valve ensures smooth, accurate, and responsive blade and ripper control—essential for productivity in high-demand mining, earthmoving, and large-scale construction environments.

Manufactured with robust materials and OEM-level quality control, our replacement control valve delivers stable pressure regulation, excellent sealing performance, and long service life, even under continuous heavy-duty operation.

   SPARKLING MACHINERY NEW 350GLC 803M 853M RE555033 EGR Valve is a dedicated emission control component exclusively designed for 350GLC excavators and 803M, 853M loaders. As a core part of the machinery’s Exhaust Gas Recirculation (EGR) system, it precisely adjusts the flow of exhaust gas back into the engine’s intake manifold—lowering combustion temperatures to reduce nitrogen oxides (NOx) emissions. This function is critical for meeting global emission standards (such as Tier 4 Final and Euro V) while preserving the engine’s power output and fuel efficiency during heavy-duty tasks like construction digging, material loading, and site grading.

   - Engineered to match original equipment performance standards, it maintains stable valve operation even under harsh working conditions, including high exhaust temperatures, continuous machinery vibration, and exposure to exhaust contaminants. It prevents valve sticking or gas leakage, avoiding emission non-compliance and engine performance issues like power loss or increased fuel consumption. Backed by strict performance verification, it guarantees long-term reliability to support both environmental compliance and uninterrupted operation of 350GLC/803M/853M machinery.

   SPARKLING MACHINERY NEW WA380 423-03-41310 Radiator is a dedicated cooling component for KOMATSU WA380 wheeled excavators (versatile for construction site material handling, road construction, and mining auxiliary tasks). As the core of the excavator’s cooling system, it efficiently dissipates heat from the engine and hydraulic oil to prevent overheating—ensuring stable performance during high-intensity operations like continuous loading, hauling, or equipment traction.
   Meeting KOMATSU OEM standards (part no. 423-03-41310), it endures -30°C to 110°C temperature fluctuations, resists dust accumulation and corrosion, and maintains consistent heat exchange efficiency. Strict performance testing guarantees seamless compatibility and long-term reliable cooling for KOMATSU WA380.
