SPARKLING Hyundai Excavator Check Valve - Durable & Precise

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 Made in China SPARKLING MACHINERY SK140SRLC/E135B Hydraulic Pump (Part Numbers: YY10V00009F4, YY10V00014F1, YY10V00009F1, YY10V00009F5) is a high-performance core component engineered for Kobelco SK140SRLC and E135B excavators. As the "heart" of the hydraulic system, it delivers consistent power transmission, ensuring smooth operation of lifting, digging, and rotating functions in heavy-duty construction scenarios. Crafted with premium materials and advanced manufacturing techniques, this pump withstands high pressure and harsh working conditions. Backed by SPARKLING’s strict quality standards, it minimizes leakage risks, reduces energy loss, and maximizes machine efficiency—your reliable choice for uninterrupted excavator performance.

   SPARKLING MACHINERY NEW 416E 416F 422F 428F 434F 361-6768 Filter GP-OI is a dedicated oil filtration component group for Caterpillar 416E, 416F, 422F, 428F, and 434F backhoe loaders/excavators (widely used in construction, mining auxiliary, and heavy material handling). As a core protective part of the equipment’s engine and hydraulic systems, it filters impurities (e.g., metal particles, sludge) from oil—preventing component wear and ensuring stable operation of key functions like engine power output and hydraulic control during high-intensity tasks.
   Meeting Caterpillar OEM standards (part no. 361-6768), it achieves 98% filtration efficiency for particles ≥10μm, endures -30°C to 100°C temperatures, resists oil corrosion, and maintains consistent flow. Strict testing guarantees seamless compatibility with the five models and long-term oil system protection.

   SPARKLING MACHINERY NEW R140LC-9 R140LC-9A R140LC-9S R160LC-9 21Q4-20812 Accel Dial Assy is a dedicated operator control component for Hyundai R140LC-9, R140LC-9A, R140LC-9S, and R160LC-9 crawler excavators (widely used in construction, municipal engineering, and medium-scale material handling). As a core part of the cab’s engine control system, it lets operators manually adjust and set engine speed levels—ensuring precise power matching for tasks like light trimming, heavy digging, or idle operation, while maintaining stable RPM to avoid unnecessary fuel waste.
   Meeting Hyundai OEM standards (part no. 21Q4-20812), it endures -30°C to 85°C temperatures, resists dust and vibration, and maintains reliable electrical contact. Strict testing guarantees seamless compatibility with the four Hyundai models and long-term accurate speed control.
