SPARKLING Backflow Prevention Valve for Hyundai Excavators

The HYUNDAI Check Valve 31N8-17420 / XKCG-00456 is a genuine replacement component designed for the main control valve system of Hyundai 9-Series crawler excavators, specifically model R300LC-9.

This check valve plays a critical role in hydraulic flow control. It allows fluid to move in one direction while preventing backflow, which protects the hydraulic system from pressure surges and maintains stable performance during demanding excavation operations.

Manufactured to OEM specifications, this valve offers precision engineering, corrosion resistance, and a durable internal seal — ensuring reliable operation, even under extreme pressure and high-duty cycles. It's ideal for both routine maintenance and emergency repairs when performance and safety are non-negotiable.

The YV22E00001F8 / YV22E00001F5 CPU Controller Unit is an original electronic control module designed specifically for KOBELCO excavators SK115SR and SK135SR. As the central brain of your machine’s electronic system, this controller ensures precise management of engine, hydraulic, and diagnostic systems, helping maintain peak performance and fuel efficiency.

Manufactured with high reliability standards, this OEM-grade controller unit is pre-programmed and ready for plug-and-play installation. It delivers accurate operational feedback, error detection, and optimized machine responsiveness, making it a critical replacement part for professional excavator maintenance.

   SPARKLING MACHINERY NEW HX330L 39K9-12100 Swing Reduction Gear is a premium China-made transmission component specifically engineered for HX330L excavators. As a critical part of the swing system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear design for minimal friction and noise, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 150118-00131 Holder Assy, Nozzle is a specialized fuel system component designed for compatible diesel engines in excavators, loaders, and heavy construction machinery. As a core part of the engine’s fuel injection system, it serves two critical roles: securely fastening the fuel nozzle in place and ensuring precise alignment with the combustion chamber. This dual function guarantees consistent fuel spray patterns and optimal atomization, which are essential for maximizing combustion efficiency, reducing exhaust emissions, and maintaining stable engine power during heavy-duty tasks like digging, hauling, and prolonged idling.

   Engineered to match original equipment performance standards, it maintains reliable functionality even under harsh engine conditions—including high operating temperatures, continuous vibration, and exposure to fuel contaminants. It prevents nozzle misalignment (a leading cause of inefficient combustion) and fuel leakage, safeguarding the engine from damage and minimizing unplanned downtime. Backed by strict performance checks, it ensures long-term reliability for the fuel injection system, supporting uninterrupted machinery operation.
