SPARKLING Rexroth 04950403 Hydraulic Component – Reliable Excavator Part

The Rexroth Relief Valve 04950403 (part no. R901102333) is a precision-engineered screw-in cartridge valve designed for hydraulic systems in excavators and industrial machinery. This robust, direct-acting spool-type valve offers pressure reducing and relieving capabilities, withstanding up to 350 bar of maximum operating pressure and supporting flow rates around 30 L/min. Constructed with quality materials and standard CAAN cavity compatibility, it ensures responsive, leak-free hydraulic control under demanding conditions.

   SPARKLING MACHINERY's new 3792809 Turbocharger is a core power-enhancing component specifically designed for Caterpillar 301.4C excavators, suitable for construction and mining applications. It enhances engine power and fuel efficiency by compressing intake air, ensuring the engine operates at optimal performance under high-load conditions.    Compliant with Caterpillar OEM standards (Part No.: 3792809), this component exhibits excellent high-temperature resistance and rotational stability, ensuring seamless compatibility with original equipment and long-term reliable operational performance.

   SPARKLING MACHINERY NEW EC330B EC360B EC330C EC700CHR SA7223-00810 Solenoid Valve is a dedicated hydraulic control component for VOLVO EC330B, EC360B, EC330C, and EC700CHR heavy crawler excavators (widely used in large-scale mining, construction, and infrastructure projects). As a core part of the excavator’s hydraulic system, it regulates the flow and direction of high-pressure hydraulic oil to key components (e.g., cylinders, motors) based on electrical signals—ensuring precise control of heavy-duty functions like boom lifting, bucket crushing, and track movement during high-intensity tasks.
   Meeting VOLVO OEM standards (part no. SA7223-00810), it endures 35 MPa hydraulic pressure, -30°C to 90°C temperatures, and resists oil corrosion and vibration. Strict testing guarantees seamless compatibility with the four VOLVO models and long-term reliable hydraulic control.

   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.
