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.

   SPARKLING MACHINERY NEW EC290B EC290C EC300D 14569767 Swing Reducer is a premium China-made transmission component specifically engineered for EC290B, EC290C, and EC300D excavators. As a critical part of the swing system, it converts high-speed, low-torque input from the hydraulic motor into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, heavy material handling, and demanding construction 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 meshing design for minimal friction, noise, and wear, it adapts seamlessly to harsh working environments, from mining sites to large-scale construction zones. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 4472-320-104 Clutch Plate S210W is a premium China-made transmission component specifically engineered for S210W wheel excavators. As a critical part of the clutch system, it enables smooth power transfer between the engine and drivetrain by creating friction to engage or disengage mechanical power, ensuring precise control during gear shifts, acceleration, and operational adjustments.

   Designed to original equipment standards, it maintains consistent friction performance and heat dissipation capabilities, operating reliably even under high-load conditions and continuous use. With optimized surface design for efficient torque transmission, it adapts seamlessly to harsh working environments, from dusty construction sites to rugged terrain. Backed by strict quality verification, it guarantees stable performance to support uninterrupted machinery operation.
