SPARKLING 31N6-75020 Check Valve – Durable Excavator Hydraulic Part

The Check Valve Double (LH & RH) is a vital component in the hydraulic control system of Hyundai R200W-7 series wheel excavators. Engineered to maintain proper flow direction and pressure stability, these valves ensure precise hydraulic operation in both left-hand and right-hand configurations.

Key Features:

• Specifically designed for Hyundai R200W-7 / R200W-7A wheel excavators

• Ensures safe and controlled hydraulic flow

• Built with corrosion-resistant, high-pressure materials

• Precision machined for tight sealing and durability

• Compatible with OEM hydraulic assemblies

   SPARKLING MACHINERY NEW EC140B EC160B EC180B VOE14557288 Remote Control Valve is a premium China-made hydraulic control component specifically engineered for EC140B, EC160B, and EC180B excavators. As a core part of the hydraulic system’s command chain, it interprets electrical or manual control signals to regulate the flow rate, pressure, and direction of hydraulic fluid to key actuators—such as boom, arm, and bucket cylinders. This enables precise, synchronized operation of excavator functions, critical for tasks like digging, grading, and material handling in construction, mining, and infrastructure projects.

   Designed to original equipment standards, it maintains stable hydraulic control even under continuous high-pressure operation and harsh working conditions (e.g., dust, vibration, and temperature swings). With optimized valve spool machining and advanced sealing technology, it minimizes pressure loss and fluid leakage, ensuring efficient energy transfer and reducing the risk of hydraulic system failures. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery operation and maximize work efficiency.

   SPARKLING MACHINERY NEW R290LC7A 110D-7E R210LC9 XKDE-01492 Tensioner is a dedicated drive system component exclusively designed for R290LC7A, 110D-7E, and R210LC9 excavators. As a core part of the excavators’ belt-driven systems (powering critical accessories like alternators, water pumps, and air compressors), it automatically maintains optimal tension in drive belts. This key function prevents belt slippage (which leads to inefficient power transmission and accessory overheating) and reduces excessive belt wear, ensuring consistent operation of essential engine auxiliary systems during heavy-duty tasks such as digging, lifting, and earthmoving.

   Engineered to match original equipment performance standards, it adapts seamlessly to dynamic working conditions—including intense vibration, temperature fluctuations, and natural belt stretch over time—without the need for manual adjustments. It safeguards the belt drive system from damage caused by loose or over-tightened belts, minimizing unplanned downtime and supporting uninterrupted excavator operation. Backed by strict performance verification, it guarantees long-term reliability for the drive system.

The CATERPILLAR 310-9497 Coupling GP – Flexible (also known as CA3109497 or 3109497) is a critical drivetrain component designed to connect the engine to the hydraulic or mechanical power transmission systems. Specifically engineered for CAT Excavators 336E, 345D, 349DL, 568FMLL, and mobile hydraulic power units, this flexible coupling provides smooth torque transmission while compensating for misalignment and vibration between components.

Compatible with Caterpillar C9.3 and C13 engines, this coupling ensures enhanced durability and performance under heavy-duty conditions. Whether operating in construction, forestry, or mining environments, the 310-9497 flexible coupling is built to OEM specifications to deliver consistent power with minimal wear and noise.

Its robust rubber-metal composite design helps absorb shock loads, reduce system stress, and protect vital engine and pump components—making it essential for maintaining operational efficiency and preventing costly downtime.
