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 EC240B EC240C EC250D EC290B EC290C 14601385 Seal Kit is a dedicated, heavy-duty sealing solution exclusively designed for VOLVO EC240B, EC240C, EC250D, EC290B, and EC290C crawler excavators—core equipment in large-scale construction, mining, and infrastructure development projects. As a critical protective component for the excavators’ high-pressure hydraulic systems, it covers key areas such as hydraulic cylinder rods, valve connections, and pump interfaces, forming robust leakproof barriers. This function is vital for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of high-load mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, gravel, or moisture from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during high-intensity tasks like rock breaking, bulk material loading, and deep excavation.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions: high hydraulic pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous heavy-duty excavator vibration. It resists oil aging and material wear, providing long-lasting protection for the hydraulic systems of EC240B/EC240C/EC250D/EC290B/EC290C models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO excavators.

The VALVE GP‑CHECK (part no. 353‑7179 / 3537179) is a precision-engineered in-line check valve designed for heavy‑duty Caterpillar equipment—including 980, 982, 982M, 982 XE wheel loaders, and the D10T2 track‑type tractor. This valve ensures reliable hydraulic pressure control and one‑way fluid flow, crucial for maintaining system integrity and preventing backflow. Built to Cat’s exacting standards, it delivers long-lasting performance in demanding environments and is available as both genuine OEM and high-quality aftermarket options.
