Whether you're maintaining a mining fleet or servicing a heavy-duty bulldozer, this main control valve assy ensures efficient operation and extended equipment lifespan.

   SPARKLING MACHINERY NEW R55W7 R55-7 11M8-42030 Radiator is a dedicated cooling system core component exclusively designed for R55W7 and R55-7 wheel excavators. As the heart of the excavators’ engine cooling system, it efficiently dissipates excess heat generated by the engine during heavy-duty operations—such as urban construction, small-scale digging, and site material handling—by transferring heat from coolant to the surrounding air. This function is critical for maintaining the engine’s optimal operating temperature (82–95°C), preventing overheating that could cause power loss, component warping, or irreversible engine damage.

   Engineered to match original equipment performance standards, it maintains high heat dissipation efficiency even under harsh working conditions, including high ambient temperatures (up to 45°C), continuous excavator vibration, and exposure to dust, debris, or rain. It resists coolant leakage and core corrosion, avoiding cooling system failures that lead to unplanned downtime or costly repairs. Backed by strict performance verification, it guarantees reliable heat management to support uninterrupted operation of R55W7/R55-7 wheel excavators.

   SPARKLING MACHINERY NEW A25D EC140C EC240C EW40D 960254 O-Ring is a dedicated sealing component exclusively engineered for VOLVO A25D articulated dump trucks, EC140C/EC240C excavators, and EW40D wheeled excavators—key equipment in construction, mining, and municipal infrastructure projects. As a critical part of the machinery’s hydraulic, fuel, and coolant systems, it creates tight, leakproof seals between mating components (e.g., hydraulic valve connections, fuel line joints, and coolant hoses). This function is essential for maintaining system pressure stability, preventing fluid leakage (hydraulic oil, fuel, coolant), and blocking dust or debris from entering internal mechanisms. It directly reduces the risk of system failures, avoids unplanned downtime, and eliminates costly repairs caused by leaks during high-intensity operations like heavy hauling, digging, or road maintenance.

   Engineered to match VOLVO’s original equipment standards, the O-ring maintains reliable sealing performance even under harsh conditions: high pressure (up to 32 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous machinery vibration. It resists fluid aging and material degradation, ensuring long-lasting protection for VOLVO A25D/EC140C/EC240C/EW40D systems. Backed by strict performance verification, it guarantees consistent sealing support for these VOLVO models.
