SPARKLING Screw‑In Spool Valve – Precision Excavator Parts

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 EC135B EC140B EC140C EC140D EC140E EC160B VOE14533604 O-Ring is a dedicated sealing component for VOLVO EC135B, EC140B/C/D/E, and EC160B crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As a core sealing part in the excavator’s hydraulic or fluid systems, it creates a tight barrier between connected components (e.g., hydraulic valves, pipe joints, cylinder covers) to prevent oil or coolant leaks during tasks like digging, loading, and slope grading.
   Meeting VOLVO OEM standards (part no. VOE14533604), it endures -35°C to 95°C temperatures, resists hydraulic oil corrosion and compression set, and maintains stable sealing performance. Strict testing guarantees seamless compatibility with the six VOLVO models and long-term leak-free 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.

   SPARKLING MACHINERY NEW EC140B EC140C EC160B EC160C EC180B EC180C VOE114589235/14524582 Valve is a dedicated, high-precision hydraulic control component exclusively engineered for VOLVO EC140B/EC140C, EC160B/EC160C, and EC180B/EC180C crawler excavators—versatile mid-sized equipment widely used in construction, municipal engineering, and light mining projects. As a core part of the excavator’s hydraulic system, it precisely regulates the flow direction and pressure of hydraulic oil to key operational mechanisms (boom, arm, bucket), ensuring smooth, responsive, and synchronized movement during tasks like trench digging, material loading, and site grading. This function is critical for maintaining stable hydraulic performance, preventing operational lags or uneven force distribution, and avoiding costly downtime caused by hydraulic system malfunctions.

   Engineered to meet VOLVO’s original equipment (OEM) standards and compatible with dual part numbers VOE114589235 and 14524582, the valve withstands harsh working conditions: high hydraulic pressure (up to 36 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil contamination, mechanical wear, and corrosion, maintaining long-lasting control accuracy. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for all six VOLVO excavator models.
