SPARKLING Cat Excavator Auxiliary Valve – Durable & Precise

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 EC250D EC250E EC300D EC300E PL3005D 14591251 Relief Valve is a dedicated hydraulic safety component for VOLVO EC250D, EC250E, EC300D, EC300E, and PL3005D crawler excavators (heavy-duty equipment for mining, large-scale construction, and infrastructure projects). As the core safety guard of the hydraulic system, it precisely limits maximum pressure to protect pumps, cylinders, and pipelines from overload damage during rock breaking, bulk ore loading, and deep excavation.

   Meeting VOLVO OEM standards (part no. 14591251), it endures 34 MPa pressure, -25°C to 105°C temperature fluctuations, and continuous vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing seamless compatibility and safe operation.

   SPARKLING MACHINERY NEW 416E 416F 422F 428F 434F 361-6768 Filter GP-OI is a dedicated oil filtration component group for Caterpillar 416E, 416F, 422F, 428F, and 434F backhoe loaders/excavators (widely used in construction, mining auxiliary, and heavy material handling). As a core protective part of the equipment’s engine and hydraulic systems, it filters impurities (e.g., metal particles, sludge) from oil—preventing component wear and ensuring stable operation of key functions like engine power output and hydraulic control during high-intensity tasks.
   Meeting Caterpillar OEM standards (part no. 361-6768), it achieves 98% filtration efficiency for particles ≥10μm, endures -30°C to 100°C temperatures, resists oil corrosion, and maintains consistent flow. Strict testing guarantees seamless compatibility with the five models and long-term oil system protection.

   SPARKLING MACHINERY NEW EC460B EC460C EC480D 14541030 Swing Reducer is a premium China-made transmission component specifically engineered for EC460B, EC460C, and EC480D excavators. As a critical part of the swing system, it converts high-speed, low-torque input from the hydraulic motor into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.​
   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction, noise, and wear, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
