   SPARKLING MACHINERY NEW HB205 HB215 PC200 PC200LL PC210 708-2L-07710 Valve Assy is a dedicated, integrated hydraulic control assembly exclusively engineered for KOMATSU HB205, HB215, PC200, PC200LL, and PC210 crawler excavators—versatile equipment widely used in construction, mining, and infrastructure projects. As a centralized control unit of the excavator’s hydraulic system, it coordinates the flow and pressure of hydraulic oil to multiple mechanisms (boom, arm, bucket, and swing), ensuring synchronized, responsive operation during tasks like trench digging, rock breaking, and material loading. This function is vital for preventing hydraulic system miscommunication, maintaining operational accuracy, and avoiding unplanned downtime caused by component misalignment.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and marked with the genuine part number 708-2L-07710, the Valve Assy withstands harsh working conditions: high hydraulic pressure (up to 34 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil contamination and mechanical wear, providing long-lasting integrated control reliability for the five KOMATSU excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load tasks.

   SPARKLING MACHINERY NEW R140W7 R140W7A R170W7 XKBF-00100 Lock Valve Kit-A is a dedicated, high-precision hydraulic safety assembly exclusively engineered for HITACHI R140W7, R140W7A, and R170W7 wheeled excavators—versatile equipment widely used in road construction, municipal engineering, and urban infrastructure projects. As a core safety component of the excavator’s hydraulic system, it locks the position of key mechanisms (boom, arm, bucket) when the excavator is stationary or during operator breaks, preventing accidental movement caused by hydraulic pressure loss. This function is vital for protecting on-site workers, avoiding equipment collisions, and ensuring operational safety during tasks like road repair, material handling, and urban demolition.

   Engineered to meet HITACHI’s original equipment (OEM) standards and marked with the genuine part number XKBF-00100, the Lock Valve Kit-A withstands harsh working conditions: high hydraulic pressure (up to 32 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from on-road travel and off-road work. It resists oil contamination and mechanical wear, providing long-lasting safety protection for the three HITACHI wheeled excavator models. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for daily excavator tasks.

   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.

   SPARKLING MACHINERY NEW CX460 CX470B CX470C LJ00981 Main Relief Valve is a dedicated, high-pressure hydraulic safety component exclusively engineered for CASE CX460, CX470B, and CX470C crawler excavators—heavy-duty equipment widely used in large-scale construction, mining, and quarrying projects. As the core safety guard of the excavator’s hydraulic system, it precisely controls and limits maximum hydraulic pressure (preventing exceeding safe thresholds), protecting critical components like hydraulic pumps, cylinders, and pipelines from damage caused by pressure spikes. This function is vital for maintaining stable hydraulic performance during high-intensity tasks (e.g., rock breaking, bulk ore loading) and avoiding costly downtime from hydraulic system failures.

   Engineered to meet CASE’s original equipment (OEM) standards and marked with the genuine part number LJ00981, the main relief valve withstands harsh working conditions: high operating pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil contamination and mechanical wear, ensuring long-lasting pressure regulation reliability for the three CASE excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load tasks.
