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 EC460B EC460C EC480D 14541030 Swing Reducer is a premium China-made transmission component specifically engineered for EC460B, EC460C, and EC480D excavators. As a critical part of the swing system, it converts high-speed, low-torque input from the hydraulic motor into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.​
   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction, noise, and wear, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW EC240B EC240C EC250D EC250E EC290B VOE22383378 Lever Sensor is a dedicated precision detection component for VOLVO EC240B, EC240C, EC250D, EC250E, and EC290B crawler excavators (widely used in construction, mining, and infrastructure projects). As a core part of the excavator’s hydraulic control system, it detects the position and movement of operation levers (e.g., boom, bucket, and arm levers) and transmits real-time signals to the ECU—ensuring precise, responsive control of hydraulic functions during tasks like digging, loading, and slope trimming.
   Meeting VOLVO OEM standards (part no. VOE22383378), it endures -30°C to 85°C temperatures, resists vibration and electrical interference, and maintains high detection accuracy. Strict testing guarantees seamless compatibility with the five VOLVO models and long-term reliable signal output.

   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.
