SPARKLING Hyundai 31N8-17420 Check Valve – Reliable Excavator Part

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 EC200B EC200D EC210 EC210B 14506889 Seal Kit is a dedicated, comprehensive sealing solution exclusively designed for VOLVO EC200B, EC200D, EC210, and EC210B excavators—workhorses in construction, mining, and infrastructure maintenance projects. As a core protective component for the excavators’ hydraulic systems, it covers critical areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming reliable leakproof barriers. This function is essential for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust or debris from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during high-intensity, prolonged operations.

   Engineered to match VOLVO’s original equipment standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 35 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous excavator vibration. It resists oil aging and wear, providing long-lasting protection for the excavators’ hydraulic systems. Backed by strict performance verification, it guarantees uninterrupted sealing support for EC200B/EC200D/EC210/EC210B excavators.

   SPARKLING MACHINERY NEW R215-7 R225-7 R290-7 14510586 Air Cleaner is a dedicated air filtration component for Hyundai R215-7, R225-7, and R290-7 crawler excavators (widely used in construction, mining, and infrastructure projects). As a core protector of the excavator’s engine, it filters dust, sand, and contaminants from incoming air before it enters the engine—preventing wear to pistons, cylinders, and valves while ensuring efficient fuel combustion during high-intensity tasks like heavy digging, rock breaking, and bulk material loading.
   Meeting Hyundai OEM standards (part no. 14510586), it achieves 99.5% filtration efficiency for particles ≥3μm, endures -30°C to 85°C temperatures, resists moisture and vibration, and maintains stable airflow. Strict testing guarantees seamless compatibility with the three Hyundai models and long-term engine protection.

   SPARKLING MACHINERY NEW R290LC9 R290LC9MH R300LC9A 39Q8-12100 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R290LC9, R290LC9MH, and R300LC9A excavators. As a critical part of the swing system, it transforms high-speed, low-torque input into low-speed, high-torque output, enabling smooth and precise rotation of the upper structure (boom, arm, and bucket) during 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 meshing 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.
