SPARKLING Hydraulic Cartridge Valve – Precision Excavator Parts

The Rexroth Relief Valve 04950403 (part no. R901102333) is a precision-engineered screw-in cartridge valve designed for hydraulic systems in excavators and industrial machinery. This robust, direct-acting spool-type valve offers pressure reducing and relieving capabilities, withstanding up to 350 bar of maximum operating pressure and supporting flow rates around 30 L/min. Constructed with quality materials and standard CAAN cavity compatibility, it ensures responsive, leak-free hydraulic control under demanding conditions.

The Main Pump Slider (Part No. 708-2L-44120) is a precision hydraulic component designed for Komatsu excavators PC210-7K, PC210-8K, and PW200-7.

This slider plays a critical role in the operation of the hydraulic main pump, ensuring smooth movement, accurate flow control, and stable pressure performance. Manufactured from high-quality materials and finished with precise machining, it is built to meet OEM dimensional and functional standards.

With a lightweight design of 0.25 kg, the main pump slider helps reduce internal friction and wear, contributing to improved pump efficiency and extended service life. It is an ideal aftermarket replacement for hydraulic system maintenance, repair, and overhaul.

   SPARKLING MACHINERY NEW EC330B EC330C EC360B EC360C VOE114659238 Compressor is a dedicated, high-performance refrigeration component exclusively engineered for VOLVO EC330B/EC330C and EC360B/EC360C crawler excavators—heavy-duty equipment critical for large-scale mining, construction, and infrastructure projects. As the core of the excavator’s air conditioning (AC) system, it compresses refrigerant to generate powerful cooling air, maintaining a stable and comfortable operator cab environment even in extreme outdoor conditions (e.g., high temperatures up to 50°C or dusty mining sites). This function is vital for preserving operator focus during long, high-intensity shifts, preventing fatigue-related errors, and ensuring consistent productivity across tasks like rock breaking, bulk ore loading, and deep excavation.

   Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE114659238, the compressor withstands harsh working conditions: high operating pressures (up to 3.0 MPa), extreme temperature fluctuations (-30°C to 85°C), and continuous heavy vibration from heavy-duty use. It resists refrigerant leakage, oil contamination, and mechanical wear, providing long-lasting cooling reliability for the four VOLVO heavy-duty excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for the excavator’s AC system.

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.
