SPARKLING D375A-3 Control Valve Assembly – Durable Excavator Part

The 709-63-11501 / 709-63-11600 Control Valve Assembly is a precision-engineered hydraulic component specifically designed for Komatsu D375A series bulldozers. As a key part of the machine’s hydraulic system, this valve ensures smooth, accurate, and responsive blade and ripper control—essential for productivity in high-demand mining, earthmoving, and large-scale construction environments.

Manufactured with robust materials and OEM-level quality control, our replacement control valve delivers stable pressure regulation, excellent sealing performance, and long service life, even under continuous heavy-duty operation.

   SPARKLING MACHINERY NEW 119266-21700 Crankshaft is a premium China-made engine core component designed for compatible construction machinery (such as excavators, loaders, and generators) and industrial engines. As the "power transmission backbone" of the engine, it converts the reciprocating motion of pistons into rotational motion to drive the machinery’s hydraulic system, undercarriage, and other key components. This critical function ensures the engine delivers consistent torque and power for heavy-duty operations—including digging, lifting, and continuous power generation—in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains exceptional structural stability even under high rotational speeds (up to industry-standard RPM thresholds) and extreme load conditions, as well as harsh working environments like vibration, temperature fluctuations, and dust. With precision-machined journals and balanced design, it minimizes friction between moving parts and reduces engine vibration. Backed by strict quality verification, it guarantees reliable power transmission to support uninterrupted machinery operation and extend overall engine service life.

   SPARKLING MACHINERY NEW EC180B EC135B EC160B 8038-00010 Seal Kit is a dedicated sealing solution exclusively designed for VOLVO EC180B, EC135B, and EC160B excavators—widely used in construction, mining, and infrastructure maintenance. As a comprehensive set of sealing components, it covers critical parts of the excavator’s hydraulic system (e.g., cylinder rods, valve connections, and pump interfaces), creating leakproof barriers to prevent hydraulic oil leakage. This function is vital for maintaining stable hydraulic pressure, ensuring smooth operation of core mechanisms (like boom lifting and arm digging), and avoiding contamination of internal components by dust or debris. It directly reduces the risk of hydraulic system failures, unplanned downtime, and costly repairs caused by oil leaks during high-intensity work.

   Engineered to match VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions—including high hydraulic pressure (up to 35 MPa), temperature fluctuations (-20°C to 100°C), and continuous machine vibration. It resists oil aging and material wear, ensuring long-term protection for the excavator’s hydraulic system. Backed by strict performance tests, it guarantees consistent sealing to support uninterrupted operation of EC180B/EC135B/EC160B excavators.

   SPARKLING MACHINERY NEW PC400 PW400MH 6151-12-1101 Cylinder Head is a premium China-made engine component specifically engineered for PC400 and PW400MH heavy machinery. As a critical part of the engine system, it seals the top of the cylinder block, houses valves, and maintains compression within combustion chambers, ensuring efficient fuel combustion and optimal engine power output in construction, mining, and industrial operations.

   Designed to original equipment standards, it maintains precise sealing performance and heat resistance even under high-temperature and high-pressure operating conditions. With optimized structural design for durability and thermal management, it adapts seamlessly to harsh working environments, from dusty job sites to heavy-load operations. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
