SPARKLING Main Control Valve Check Valve – Durable 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 119266-21700 Crankshaft is a premium China-made engine core component designed for compatible construction machinery (such as excavators, loaders, and generators) and industrial engines. As the "power transmission backbone" of the engine, it converts the reciprocating motion of pistons into rotational motion to drive the machinery’s hydraulic system, undercarriage, and other key components. This critical function ensures the engine delivers consistent torque and power for heavy-duty operations—including digging, lifting, and continuous power generation—in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains exceptional structural stability even under high rotational speeds (up to industry-standard RPM thresholds) and extreme load conditions, as well as harsh working environments like vibration, temperature fluctuations, and dust. With precision-machined journals and balanced design, it minimizes friction between moving parts and reduces engine vibration. Backed by strict quality verification, it guarantees reliable power transmission to support uninterrupted machinery operation and extend overall engine service life.

   SPARKLING MACHINERY NEW EC250D EC300D VOE14694152 Hose is a dedicated flexible fluid transmission component for VOLVO EC250D and EC300D crawler excavators (widely used in medium-to-large construction, mining auxiliary operations, and infrastructure projects). As a core part of the excavator’s hydraulic system, it transfers high-pressure hydraulic oil between key components (e.g., hydraulic pumps, cylinders, control valves) to ensure uninterrupted power supply for tasks like digging, rock breaking, and material loading.
   Meeting VOLVO OEM standards (part no. VOE14694152), it endures 30 MPa hydraulic pressure, -35°C to 95°C temperature fluctuations, and repeated bending. Strict performance testing guarantees seamless compatibility with the two VOLVO models and long-term leak-free, reliable fluid transmission.

   SPARKLING MACHINERY NEW 14652656 Center Swivel Joint is a premium China-made hydraulic connection component designed for compatible excavators. As a critical link between the excavator’s fixed lower structure (undercarriage) and rotating upper structure (cabin, boom), it enables continuous 360° rotation while maintaining seamless hydraulic fluid transmission to key systems—such as the swing motor, hydraulic cylinders, and control valves. This ensures unobstructed, reliable power delivery for core operations like digging, lifting, and swing movements in construction, mining, and earthmoving tasks.

   Engineered to original equipment standards, it maintains leak-free performance even under high hydraulic pressure and continuous rotational stress, as well as harsh working conditions (e.g., dust, vibration, and exposure to construction debris). With optimized sealing rings and precision-machined internal channels, it minimizes pressure loss and prevents fluid contamination, safeguarding the hydraulic system from damage. Backed by strict quality verification, it guarantees consistent operation to support uninterrupted machinery rotation and maximize work efficiency.
