MADE IN CHINA SPARKLING MACHINERY NEW VOE14726298 PRINTED CIRCUIT BOARD
SPARKLING MACHINERY NEW VOE14726298 Printed Circuit Board (PCB) is a premium China-made electrical control component designed for compatible excavators and heavy construction machinery. As the "nerve center" of the machinery’s electrical system, it integrates and connects key electronic components—such as microchips, sensors, and connectors—to enable seamless data transmission and signal processing. This supports critical machinery functions, including engine control, hydraulic system regulation, cabin electronics management, and fault diagnosis, ensuring synchronized, reliable operation in construction, mining, and earthmoving tasks.
Engineered to original equipment standards, it maintains stable electrical performance even under harsh working conditions, such as intense vibration, temperature fluctuations (-30°C to 85°C), and exposure to dust or moisture. With optimized circuit layout for minimal signal interference and a rugged protective coating, it resists environmental wear and electrical failures. Backed by strict quality verification, it guarantees consistent functionality to support uninterrupted machinery operation and reduce downtime caused by electrical system malfunctions.

KOBELCO EXCAVATOR PARTS MADE IN CHINA NEW SK40SR 30SR-2 30SR-3 PM30V00019F4 PILOT VALVE SPARKLING MACHINERY
SPARKLING MACHINERY NEW SK40SR 30SR-2 30SR-3 PM30V00019F4 Pilot Valve is a dedicated, high-sensitivity hydraulic control component exclusively engineered for KOBELCO SK40SR, 30SR-2, and 30SR-3 mini crawler excavators—versatile equipment widely used in urban construction, landscaping, and indoor demolition projects. As a key “control switch” of the excavator’s hydraulic system, it converts low-pressure pilot oil signals into precise control commands to operate main hydraulic valves, enabling smooth, fine-tuned movement of the boom, arm, and bucket during tasks like trench digging, small-scale material handling, and narrow-space construction. This function is vital for ensuring operational agility, preventing hydraulic overshoot, and avoiding unplanned downtime caused by control lag.
Engineered to meet KOBELCO’s original equipment (OEM) standards and marked with the genuine part number PM30V00019F4, the Pilot Valve withstands harsh working conditions: low to moderate hydraulic pressure (up to 5 MPa), extreme temperature fluctuations (-30°C to 85°C), and continuous vibration from light-duty use. It resists oil contamination and mechanical wear, providing long-lasting control reliability for the three KOBELCO mini excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily tasks.
