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.

The Solenoid Valve YN22V00035F1 is a high-performance hydraulic overload relief valve designed for medium to large Kobelco excavators—compatible with models such as SK260-9, SK350-9, SK170-8, SK210-8, SK210-9, SK295-8, and many more. This robust solenoid valve delivers accurate hydraulic control and swift pressure relief to protect key hydraulic circuits during heavy-duty operation. Built to OEM-quality standards, it offers reliable performance and plug-and-play installation in demanding working environments.

The Made in China SPARKLING MACHINERY SK140SRLC/E135B Hydraulic Pump (Part Numbers: YY10V00009F4, YY10V00014F1, YY10V00009F1, YY10V00009F5) is a high-performance core component engineered for Kobelco SK140SRLC and E135B excavators. As the "heart" of the hydraulic system, it delivers consistent power transmission, ensuring smooth operation of lifting, digging, and rotating functions in heavy-duty construction scenarios. Crafted with premium materials and advanced manufacturing techniques, this pump withstands high pressure and harsh working conditions. Backed by SPARKLING’s strict quality standards, it minimizes leakage risks, reduces energy loss, and maximizes machine efficiency—your reliable choice for uninterrupted excavator performance.

   SPARKLING MACHINERY NEW 420F 428E 428F 430F 432E 432F 360-7435 Valve GP-Rel is a dedicated hydraulic relief valve group for Caterpillar 420F, 428E, 428F, 430F, 432E, and 432F backhoe loaders/excavators (widely used in construction, mining auxiliary, and municipal infrastructure projects). As a core safety component of the equipment’s hydraulic system, it regulates and limits maximum hydraulic pressure—preventing overpressure damage to pumps, cylinders, and valves during high-intensity tasks like heavy digging, material loading, and backhoe operation.
   Meeting Caterpillar OEM standards (part no. 360-7435), it endures 32 MPa maximum pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains stable pressure relief performance. Strict testing guarantees seamless compatibility with the six Caterpillar models and long-term hydraulic system protection.
