SPARKLING R901102333 Excavator Part – Durable & Precise

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 EC140B EC160B EC180B EC460CHR 14514215 Cont Valve is a premium China-made hydraulic component specifically engineered for EC140B, EC160B, EC180B, and EC460CHR excavators. As a critical part of the hydraulic system, it regulates fluid flow, pressure, and direction to control the operation of actuators such as booms, arms, and buckets, ensuring precise and responsive machinery movement in construction, mining, and heavy-duty applications.

   Designed to original equipment standards, it maintains stable hydraulic control and efficient energy transfer even under continuous high-pressure operation. With optimized valve spool design for minimal pressure loss, it adapts seamlessly to harsh working environments, from dusty job sites to wet conditions. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW R360LC7A 21NA-34100 Controller is a dedicated electronic control unit for Hyundai R360LC7A crawler excavators (widely used in construction, mining, and large-scale infrastructure projects). As the "brain" of the excavator, it processes real-time data from sensors (e.g., engine, hydraulic, and operator controls) to regulate key functions—such as engine speed, hydraulic flow, and bucket operation—ensuring coordinated, efficient performance during high-intensity tasks like heavy digging and rock breaking.
   Meeting Hyundai OEM standards (part no. 21NA-34100), it endures -30°C to 85°C temperatures, resists electromagnetic interference and vibration, and maintains stable data transmission. Strict testing guarantees seamless compatibility with Hyundai R360LC7A and long-term reliable equipment control.

The CATERPILLAR COVER ASSY 4T-1572 is a robust and precision-engineered component designed for heavy-duty CAT machines, including models like 772B, 768C, 773D, 775F, and 773F. This cover assembly plays a critical role in protecting internal systems from dust, moisture, and impact in demanding working environments. Manufactured with high-strength materials and built to OEM standards, it offers reliable sealing and long-lasting performance.

Compatible part numbers include 4T-1572, 4T1572, and CA4T1572. Whether for maintenance or replacement, this part ensures a perfect fit and optimal function, helping reduce downtime and extend equipment life.
