   SPARKLING MACHINERY NEW EC250D EC290B EC290C 14616531 Solenoid Valve is a premium China-made hydraulic control component specifically engineered for EC250D, EC290B, and EC290C excavators. As a critical part of the hydraulic and electrical system interface, it uses electromagnetic signals to control fluid flow direction, pressure, and flow rate, enabling precise activation of hydraulic actuators such as cylinders and motors during operational tasks.

   Designed to original equipment standards, it maintains rapid response times and stable switching performance even under continuous electrical and hydraulic stress. With optimized valve body design for minimal pressure loss, it adapts seamlessly to harsh working environments, from dusty construction sites to wet conditions. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 336GC 340GC 345GC 350GC 510-1695/617-1905 Injector is a core engine fuel injection component for Caterpillar 336GC, 340GC, 345GC, and 350GC excavators (widely used in heavy construction, mining, and large-scale infrastructure projects). As the "fuel atomization core", it precisely sprays fuel into the combustion chamber—ensuring efficient fuel combustion during high-intensity tasks like rock breaking, deep digging, and heavy lifting, while maintaining stable engine power output and reducing fuel waste.
   Meeting Caterpillar OEM standards (part nos. 510-1695/617-1905), it endures -30°C to 200°C engine temperatures, resists fuel corrosion and vibration, and guarantees consistent injection pressure. Strict testing ensures seamless compatibility with the four Caterpillar models and long-term engine reliability.
