SPARKLING SEM Radiator 539‑1100 – Reliable Excavator Cooling Solution

The SEM Radiator 539‑1100 is a durable cooling system designed for SEM and Caterpillar machinery. Precisely engineered by Cat, this radiator maintains optimal engine temperature under heavy-duty conditions. Featuring premium materials and OEM-grade construction, it delivers enhanced corrosion resistance and long-term reliability—backed by Cat’s global parts support network

   SPARKLING MACHINERY NEW 119266-21700 Crankshaft is a premium China-made engine core component designed for compatible construction machinery (such as excavators, loaders, and generators) and industrial engines. As the "power transmission backbone" of the engine, it converts the reciprocating motion of pistons into rotational motion to drive the machinery’s hydraulic system, undercarriage, and other key components. This critical function ensures the engine delivers consistent torque and power for heavy-duty operations—including digging, lifting, and continuous power generation—in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains exceptional structural stability even under high rotational speeds (up to industry-standard RPM thresholds) and extreme load conditions, as well as harsh working environments like vibration, temperature fluctuations, and dust. With precision-machined journals and balanced design, it minimizes friction between moving parts and reduces engine vibration. Backed by strict quality verification, it guarantees reliable power transmission to support uninterrupted machinery operation and extend overall engine service life.

Precision Hydraulic Control Valve for E235BSR Series Crawler Excavators
Engineered for E235BSR, E235BSRLC, and E235BSRNLC crawler excavators, the Hydraulic Control Valve (YF30V00011F1/F3/F4) is the intelligent nerve center of your machine’s hydraulic system. This OEM-compatible valve integrates advanced flow distribution and pressure regulation technologies, enabling seamless coordination of multiple actuators (boom, arm, swing, travel) under heavy loads. Featuring hardened spools with laser-etched metering profiles and triple-layer Nitrile seals6, it minimizes internal leakage, reduces heat generation, and eliminates sudden pressure drops during complex compound operations. Rigorously tested to exceed 500,000 cycles at 350 bar4, SPARKLING MACHINERY’s valve ensures precise controllability in demanding applications – from trenching to lifting – while extending pump life by stabilizing system pressure fluctuations.

   SPARKLING MACHINERY NEW SK235SRLC-1E SK235SR-1E SK235SRNLC-1E SK200LC-6ES YN30V00095F1 Pilot Valve is a dedicated hydraulic control component for Kobelco SK235SRLC-1E, SK235SR-1E, SK235SRNLC-1E, and SK200LC-6ES crawler excavators (widely used in construction, municipal engineering, and light mining). As the "hydraulic control precursor", it regulates low-pressure pilot oil to control the operation of main hydraulic valves—enabling precise adjustment of boom, bucket, and swing movements during tasks like digging, loading, and site trimming, while ensuring responsive and smooth equipment operation.
   Meeting Kobelco OEM standards (part no. YN30V00095F1), it endures 5 MPa pilot pressure, -30°C to 90°C temperatures, resists hydraulic oil corrosion and vibration, and maintains stable flow control. Strict testing guarantees seamless compatibility with the four Kobelco models and long-term hydraulic system reliability.
