SPARKLING KTJ11660 Hydraulic Valve – Precision Excavator Part

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.

The Valve GP‑Manual (Cat part no. 389‑2407 / CA3892407) is a rugged manual auxiliary shut‑off valve designed for use in heavy-duty Caterpillar excavators—specifically models 352, 323F, 320C, 320D SA, M325D MH/L, 355, and more. It provides dependable two-way hydraulic shut-off control, helping protect critical systems during maintenance or attachments handling. Built to OEM tolerance, this valve ensures reliable operation in the harshest environments, available both as a genuine Cat part and high-quality aftermarket alternative.

    SPARKLING MACHINERY NEW EC240C EC250D EC250E EC290B EC300E 14596398 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC240C, EC250D, EC250E, EC290B, and EC300E crawler excavators—heavy-duty equipment critical for large-scale construction, mining, and infrastructure projects. As a core protective component for the excavators’ high-pressure hydraulic systems, it covers key areas including 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 wear, providing long-lasting protection for the hydraulic systems of EC240C/EC250D/EC250E/EC290B/EC300E models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO excavators.

   SPARKLING MACHINERY NEW R200W7 51N6-30420 (LINK(B) ASSY-RH) & 51N6-30410 (LINK(B) ASSY-LH) is a pair of dedicated structural linkage assemblies exclusively designed for R200W7 wheel excavators. As core components of the excavator’s working mechanism, the right-hand (RH) and left-hand (LH) link assemblies work in tandem to connect critical moving parts (boom, arm, and bucket)，enabling smooth, coordinated hydraulic-driven movements. This function is essential for supporting heavy-duty tasks like road construction, material loading, and site leveling—directly ensuring the excavator’s operational precision, load-bearing stability, and resistance to mechanical jams during prolonged high-intensity work.

   Engineered to match original equipment performance standards, both assemblies maintain strong structural integrity and wear resistance even under harsh conditions (continuous load stress, vibration, dust/debris exposure). They resist deformation and connection loosening, avoiding mechanical failures that could lead to unplanned downtime or costly component damage. Backed by strict performance verification, the pair guarantees long-term reliability to support uninterrupted operation of R200W7 wheel excavators.
