   SPARKLING MACHINERY NEW 416E 416F 420F 422E 422F 308-2890 Kit-Regulato is a dedicated hydraulic regulation component kit for Caterpillar 416E, 416F, 420F, 422E, and 422F backhoe loaders/excavators (widely used in construction, municipal engineering, and agricultural operations). As a core set for the equipment’s hydraulic system, it fine-tunes pressure, flow, and valve response to ensure consistent performance of key functions—like buc   Your Caterpillar’s trusted hydraulic regulation solution starts here. 
   Now, we’re proud to present the CATERPILLAR EXCAVATOR PARTS MADE IN CHINA NEW 416E 416F 420F 422E 422F 308-2890 KIT-REGULATO by SPARKLING MACHINERY. Next, we’ll cover its core strengths: seamless compatibility with five Caterpillar models, precise hydraulic tuning, rigorous quality, and more—helping you see how it boosts your equipment’s operational consistency and cuts maintenance troubles.ket digging, boom lifting, and steering—even under variable workloads.
   Meeting Caterpillar OEM standards (part no. 308-2890), it endures 28 MPa hydraulic pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains stable regulation. Strict testing guarantees seamless compatibility with the five models and long-term hydraulic system efficiency.

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 EC250D EC300D PL3005D VOE14631900 11220933 14406900 Hose is a dedicated hydraulic fluid transfer component for VOLVO EC250D, EC300D, and PL3005D crawler excavators (heavy-duty equipment for mining, large-scale construction, and infrastructure projects). As a key part of the hydraulic system, it securely conveys hydraulic oil between pumps, valves, and cylinders, ensuring uninterrupted power for high-intensity tasks like rock breaking, bulk ore loading, and deep excavation.
   Meeting VOLVO OEM standards (compatible with part nos. VOE14631900, 11220933, 14406900), it endures 34 MPa pressure, -30°C to 105°C temperature fluctuations, and continuous vibration. It resists oil aging and external abrasion, ensuring long-term leak-free performance for the three VOLVO models, with strict testing guaranteeing seamless compatibility and reliable operation.
