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 Caterpillar Coupling-Pump (Part No. 267-1082 / CA2671082 / 2671082) is a high-quality aftermarket replacement part made in China, engineered to fit CAT mini hydraulic excavators such as 305C CR, 305.5E, and certain Caterpillar wheel loader models.

This coupling serves as a crucial link between the engine and hydraulic pump, ensuring efficient power transmission while absorbing vibration and reducing stress on connected components. Built from durable elastomeric and metal materials, it offers excellent torsional flexibility and resistance to wear — helping maintain optimal machine performance.

If you're looking for a cost-effective yet reliable alternative to OEM parts, this China-made coupling is a smart choice for equipment maintenance and repair, without compromising functional integrity.

   SPARKLING MACHINERY NEW YN30V00171F1 Selector Valve is a dedicated, high-precision hydraulic control component exclusively engineered for compatible KAWASAKI excavator models—versatile equipment widely used in construction, mining, and infrastructure maintenance projects. As a core part of the excavator’s hydraulic system, it precisely switches the direction of hydraulic oil flow to key mechanisms (boom, arm, bucket, or auxiliary tools), enabling smooth, on-demand operation of different functions during tasks like trench digging, material loading, and rock breaking. This function is vital for ensuring flexible operational control, preventing hydraulic flow misdirection, and avoiding unplanned downtime caused by system inefficiencies or component misalignment.

   Engineered to meet KAWASAKI’s original equipment (OEM) standards and marked with the genuine part number YN30V00171F1, the selector valve withstands harsh working conditions: high hydraulic pressure (up to 35 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil contamination and mechanical wear, maintaining stable control performance for long periods. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for applicable KAWASAKI excavator models.
