MADE IN CHINA SPARKLING MACHINERY NEW 8-98238255-2 EGR VALVE
SPARKLING MACHINERY NEW 8-98238255-2 EGR Valve is a premium China-made emissions control component designed for compatible diesel-powered construction machinery (such as excavators, loaders) and industrial engines. As a core part of the Exhaust Gas Recirculation (EGR) system, it precisely regulates the flow of exhaust gas back into the engine’s intake manifold—reducing the combustion temperature to minimize the formation of nitrogen oxides (NOx), a major harmful emission. This ensures compliance with global emission standards (e.g., Tier 4 Final, Euro V) while maintaining engine power output for heavy-duty tasks like digging, lifting, and material handling in construction, mining, and urban infrastructure projects.
Engineered to original equipment standards, it maintains reliable performance even under harsh working conditions, including high exhaust temperatures (up to 650°C), vibration, and exposure to soot or exhaust contaminants. With a precision-machined valve stem and adaptive sealing design, it minimizes gas leakage and ensures smooth, responsive flow control. Backed by strict quality verification, it guarantees consistent emissions reduction and prevents EGR system-related engine issues, supporting uninterrupted machinery operation.

Caterpillar EXCAVATOR PARTS MADE IN CHINA NEW 306E 307E 308E 423-4562 SOLENOID ASSY SPARKLING MACHINERY
SPARKLING MACHINERY NEW 306E 307E 308E 423-4562 Solenoid Assy is a dedicated electrical control component for Caterpillar 306E, 307E, and 308E mini crawler excavators (versatile for landscaping, indoor demolition, and small-scale construction). As a key part of the excavator’s hydraulic or fuel system, it integrates solenoid and accessory components to convert electrical signals into mechanical action—controlling valve actuation or fuel flow to ensure precise operation of functions like bucket tilting and arm movement during delicate tasks.
Meeting Caterpillar OEM standards (part no. 423-4562), it endures -30°C to 85°C temperatures, resists vibration and electrical interference, and maintains stable switching performance. Strict testing guarantees seamless compatibility and long-term reliability for the three Caterpillar models.
