Hydraulic Control Valve Assembly KTJ14351 / KTJ11660 for CASE CX470B Excavator

The KTJ14351 / KTJ11660 Hydraulic Control Valve Assembly is a high-performance OEM-compatible part specifically designed for the CASE CX470B excavator. Manufactured by SPARKLING MACHINERY, this control valve ensures precise and responsive hydraulic fluid distribution to key working functions such as boom, arm, bucket, and travel.

This unit is built for heavy-duty operation, delivering accurate flow control under high pressure. Ideal for demanding excavation, lifting, or demolition work, the assembly maintains the machine's power, speed, and stability while minimizing hydraulic losses.

   SPARKLING MACHINERY NEW CX300C CX350C LJ018980 Solenoid Valve is a dedicated hydraulic control component exclusively designed for CX300C and CX350C excavators. As a key part of the excavators’ hydraulic system, it precisely regulates the flow and direction of hydraulic oil to control critical working mechanisms—including boom lifting, arm movement, and bucket operation. This function is essential for achieving smooth, responsive hydraulic performance during heavy-duty tasks like deep digging, large-volume material loading, and mining operations, where precise control directly impacts work efficiency and task accuracy.

   Engineered to match original equipment performance standards, it maintains stable valve operation even under harsh working conditions, such as high hydraulic pressure, continuous vibration, and temperature fluctuations. It prevents oil leakage and hydraulic signal lag, avoiding unresponsive movements or uneven mechanism operation. Backed by strict performance verification, it guarantees long-term reliability to support uninterrupted operation of CX300C and CX350C excavators.

   SPARKLING MACHINERY NEW PC490 708-1T-13450/708-1T-13620 Plate, Valve is a dedicated, high-precision hydraulic sealing component exclusively engineered for KOMATSU PC490 crawler excavators—heavy-duty equipment widely used in large-scale mining, construction, and quarrying projects. As a core sealing and pressure-regulating part of the excavator’s hydraulic valve assembly, it ensures tight sealing between valve components and assists in maintaining stable hydraulic pressure, preventing oil leakage and pressure loss during high-intensity tasks like rock breaking, bulk ore loading, and deep excavation. This function is vital for preserving hydraulic system efficiency, avoiding component damage from contamination, and reducing unplanned downtime that disrupts critical project workflows.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and compatible with part numbers 708-1T-13450 and 708-1T-13620, the Valve Plate withstands harsh working conditions: high hydraulic pressure (up to 36 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil corrosion and mechanical wear, providing long-lasting sealing and pressure support for KOMATSU PC490 excavators. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for daily high-load tasks.
