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 EC135B EC140B EC160B EC180B EC210B EW145B VOE120459863 Pully is a dedicated, heavy-duty mechanical component exclusively engineered for VOLVO EC135B, EC140B, EC160B, EC180B, EC210B crawler excavators and EW145B wheeled excavator—versatile mid-sized equipment widely used in construction, municipal engineering, and light mining projects. As a core part of the excavator’s accessory drive system, it enables smooth belt operation to power critical auxiliary components (e.g., water pumps, alternators, hydraulic oil coolers). This function is vital for maintaining stable engine and hydraulic system performance during tasks like trench digging, material loading, and site grading, preventing belt slippage, drive system inefficiencies, or unexpected downtime caused by auxiliary component failure.

   Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE120459863, the pully withstands harsh working conditions: high rotational speeds (up to 3,200 RPM), extreme temperature fluctuations (-25°C to 110°C), and continuous vibration from both on-road (EW145B) and off-road (crawler models) use. It maintains precise belt alignment and resists wear, providing long-lasting reliability for the excavators’ drive systems. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for all six VOLVO models.

   SPARKLING MACHINERY NEW 4719202 Heater is a core climate control component for Hitachi ZX140W-3/ZX140W-3-AMS/ZX145W-3/ZX400W-3 excavators (construction/mining use). It heats cabin air via engine coolant circulation, delivering consistent warmth to ensure comfortable and safe operation in low temperatures. 
   Meeting Hitachi OEM standards (4719202), it resists -30°C to 120°C temps, corrosion, and coolant contamination, guaranteeing seamless compatibility and reliable long-term heating performance.

   SPARKLING MACHINERY NEW 7114-32560 Brake Disc EW170 is a premium China-made safety component specifically engineered for EW170 wheel excavators. As a critical part of the braking system, it works with brake pads to generate controlled friction, converting kinetic energy into heat to slow or stop the machinery, ensuring precise stopping power during operation, maneuvering, and emergency situations.

   Designed to original equipment standards, it maintains consistent heat dissipation and wear resistance, performing reliably even under frequent braking and heavy-load conditions. With optimized structural design for uniform force distribution, it adapts seamlessly to harsh working environments, from muddy construction sites to high-temperature climates. Backed by strict quality verification, it guarantees stable performance to support safe and uninterrupted machinery operation.
