CASE Excavator Hydraulic Valve Replacement

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 ED150 SK200LC-6ES SK235SR-1ES SK210-8 YR35V00009S022 Solenoid Valve Assy is a dedicated hydraulic-electronic control assembly for Kobelco ED150, SK200LC-6ES, SK235SR-1ES, and SK210-8 excavators (widely used in construction, municipal engineering, and light mining). As the "hydraulic command hub", it uses electrical signals to control oil flow, pressure, and direction—regulating key functions like boom lifting, bucket digging, and swing movements, ensuring precise, responsive operation during high-intensity tasks.
   Meeting Kobelco OEM standards (part no. YR35V00009S022), it endures 28 MPa working pressure, -30°C to 90°C temperatures, resists oil corrosion and vibration, and maintains stable signal transmission. Strict testing guarantees seamless compatibility with the four Kobelco models and long-term hydraulic-electronic system reliability.

   SPARKLING MACHINERY NEW X220571211 Radiator is a critical cooling system component designed for compatible construction machinery, including excavators and loaders. As the core of the machinery’s heat dissipation system, it efficiently cools engine coolant by transferring heat from the coolant to the surrounding air—preventing engine overheating during heavy-duty operations like prolonged digging, high-load lifting, and continuous idling in construction, mining, or infrastructure projects. This function is essential for maintaining the engine’s optimal operating temperature, which directly impacts fuel efficiency, power output, and long-term service life.

   Engineered to match original equipment performance standards, it maintains high heat dissipation efficiency even under harsh working conditions, such as high ambient temperatures, dust accumulation, and vibration. It resists coolant leakage and blockages, avoiding cooling system failures that could lead to costly engine damage. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 440-00257 Cylinder;Arm is a dedicated hydraulic actuation component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s arm movement system, it converts hydraulic pressure into linear force to drive the arm’s lifting, lowering, and extending actions—supporting critical on-site tasks like digging, material grabbing, and precision placement in construction, mining, or infrastructure projects. This function is essential for maintaining the machinery’s operational flexibility and load-bearing capacity, directly ensuring smooth coordination between the arm and bucket, and preventing movement lag or jams that could reduce work efficiency or cause safety hazards.

   Engineered to match original equipment performance standards, it maintains stable pressure retention and smooth piston movement even under harsh working conditions, including heavy load stress (up to rated 500 kN), continuous vibration, and exposure to dust or hydraulic oil contaminants. It resists internal leakage and cylinder wall wear, avoiding hydraulic system inefficiencies that lead to unplanned downtime. Backed by strict performance verification, it guarantees reliable arm actuation to support uninterrupted operation of compatible heavy-duty machinery.
