SPARKLING EW145B Boom Holding Valve – Reliable Excavator Hydraulic Part

The Volvo Excavator Valve (part no. VOE 14531325 / 14531325) is a high-quality hydraulic control/relief valve suitable for medium-class Volvo excavators—models include EC135B, EC140B/D, EC200B/D, EC210B, EC240B/C, EC290B/C, and compact wheeled excavators like EW145B, as well as other industrial machinery from tractor cranes to graders. Built to OEM standards and offered in both genuine and aftermarket versions, this valve ensures precise hydraulic pressure regulation and boom-arm holding, safeguarding operator control and machine performance on challenging job sites.

   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.

   SPARKLING MACHINERY NEW ZX30 ZX35 ZX40U 4434315 Radiator is a dedicated cooling system component exclusively designed for ZX30, ZX35, and ZX40U mini excavators. As the core of these machines’ heat dissipation systems, it efficiently transfers heat from engine coolant to the surrounding air—preventing engine overheating during tasks like urban landscaping, small-scale construction, and agricultural maintenance. This function is critical for maintaining the excavators’ optimal operating temperature (typically 82–95°C), which directly ensures stable engine power output, fuel efficiency, and long-term service life of key engine components.

   Engineered to match original equipment performance standards, it retains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous machine vibration. It resists coolant leakage and internal blockages, avoiding cooling system failures that could lead to unplanned downtime or costly engine damage. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of ZX30/ZX35/ZX40U excavators.

   SPARKLING MACHINERY NEW R200W7 R170W7 31N6-10150 31N6-10160 Reduction Gear is a premium China-made transmission component specifically engineered for R200W7 and R170W7 wheel excavators. As a critical part of the power transmission system, it adjusts power output by converting high-speed, low-torque input into low-speed, high-torque motion, enabling efficient operation of key mechanical functions such as swing, travel, or auxiliary movements during construction, material handling, and industrial tasks.

   Designed to original equipment standards, it maintains stable power transfer and optimal torque conversion even under continuous operational stress and heavy loads. With optimized gear meshing design for minimal friction and wear, it adapts seamlessly to harsh working environments, from dusty job sites to rough terrain. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
