Bosch Rexroth Valve 04950403850400A

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 NEW 7114-17620 Brake Disc EW130 is a premium China-made safety component specifically engineered for EW130 wheel excavators. As a core part of the braking system, it collaborates with brake pads to generate controlled friction, converting kinetic energy into heat to enable smooth deceleration and precise stopping during operation, maneuvering, and emergency situations.

   Designed to original equipment standards, it maintains consistent heat dissipation efficiency and wear resistance, performing reliably even under frequent braking cycles and heavy-load conditions. With optimized structural design for uniform force distribution, it adapts seamlessly to harsh working environments, from muddy construction sites to high-temperature climates. Backed by strict quality verification, it guarantees stable performance to support safe and uninterrupted machinery operation.

   SPARKLING MACHINERY NEW EC240B EC240C FC2924C 14531594 Hydraulic Pump is a premium China-made power component specifically engineered for EC240B, EC240C, and FC2924C excavators. As the core of the hydraulic system, it converts mechanical energy into hydraulic pressure, driving critical operations such as boom lifting, arm articulation, and bucket movement through controlled fluid flow. This ensures efficient power transmission and responsive machinery performance in construction, mining, and heavy-duty earthmoving applications.​
   Designed to original equipment standards, it maintains stable pressure output and consistent flow rates even under continuous high-load operation. With optimized internal design for minimal energy loss and enhanced wear resistance, it adapts seamlessly to harsh working environments, from dusty job sites to high-temperature conditions. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery operation.

   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.
