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 EC55C EC60C EC60E ECR58D ECR88D 14576751 Solenoid Valve is a critical hydraulic control component for Volvo EC55C, EC60C, EC60E, ECR58D, and ECR88D excavators (widely used in small-scale construction, landscaping, and municipal maintenance). As the "hydraulic flow regulator", it precisely controls the on/off and direction of hydraulic oil for key functions like bucket tilting, arm lifting, and auxiliary tool operation—ensuring responsive and smooth performance during light-duty tasks, while preventing oil leaks or pressure mismatches that reduce equipment efficiency.
   Meeting Volvo OEM standards (part no. 14576751), it withstands -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees stable electromagnetic switching. Strict testing ensures seamless compatibility with the five Volvo models and long-term reliability of the hydraulic system.

   The Wheeled Excavators Spare Parts 31Q6-20013 (LH) / 31Q6-20023 (RH) RCV LEVER ASSY is a premium operational control component meticulously engineered for Hyundai Construction Equipment, specifically tailored to meet the precision maneuvering demands of R140W-9, R170W-9, and R210W-9 wheeled excavators. As critical parts of the machinery’s hydraulic remote control valve (RCV) system, these left-hand (LH) and right-hand (RH) lever assemblies enable operators to intuitively control key excavator functions—including boom lifting/lowering, arm extension/retraction, bucket digging/dumping, and swing/wheeled mobility—with precise, responsive input. 
   Designed to seamlessly integrate with Hyundai’s RCV system and operator cab layout, the lever assemblies ensure smooth operational control, reduce operator fatigue, and enhance work efficiency even during prolonged heavy-duty construction tasks.

Key Features
· Dual-part number configuration: 31Q6-20013 (LH) and 31Q6-20023 (RH) for complete left/right control compatibility
· Custom-engineered for perfect fit with Hyundai R140W-9, R170W-9, R210W-9 wheeled excavators’ RCV systems
· Ergonomic design with optimized grip and lever resistance for comfortable, precise operation
· Durable internal linkage and spring mechanisms for consistent response and long-term reliability
· Strict adherence to Hyundai OEM specifications for seamless integration and consistent control performance

Compatible Models
· Hyundai Construction Equipment Wheeled Excavators: R140W-9, R170W-9, R210W-9

   SPARKLING MACHINERY NEW EX270 EX270-5 EX280H-5 EX300 EX300-2 EX300-3 4067720 Bushing is a critical wear-resistant component for Hitachi EX270, EX270-5, EX280H-5, EX300, EX300-2, and EX300-3 excavators (widely used in construction, mining, and earthmoving projects). As the "joint buffer", it reduces friction between moving parts (e.g., boom hinges, arm connections) during tasks like digging, lifting, and swing operations—preventing metal-to-metal wear, absorbing vibration, and ensuring smooth movement of hydraulic structures.
   Meeting Hitachi OEM standards (part no. 4067720), it endures -30°C to 100°C working temperatures, resists corrosion and impact, and maintains stable dimensional accuracy. Strict testing guarantees seamless compatibility with the six Hitachi models and long-term reliability of excavator structural joints.
