   SPARKLING MACHINERY NEW EC120D EC135B EC140B EC140C EC140D 14509331 Expansion Valve is a dedicated thermal control component for VOLVO EC120D, EC135B, EC140B, EC140C, and EC140D crawler excavators (mid-sized equipment for construction, municipal engineering, and landscaping). As a key part of the excavator’s air conditioning system, it precisely regulates refrigerant flow to maintain stable cabin temperature, ensuring operator comfort during long-hour tasks in hot or cold environments.

   Meeting VOLVO OEM standards (part no. 14509331), it endures -30°C to 80°C temperature fluctuations, resists refrigerant corrosion and mechanical wear, and ensures consistent thermal control for the five VOLVO models. Strict performance testing guarantees seamless compatibility and reliable operation.

   SPARKLING MACHINERY NEW VOE114059740 Seat is a dedicated operator comfort component designed for compatible construction machinery, such as excavators and loaders. As a core part of the machinery’s cabin setup, it provides ergonomic support for operators during long-hour heavy-duty operations—including adjustable backrest angles, lumbar support, and cushion firmness. This design reduces operator fatigue caused by prolonged sitting, vibration, and repetitive movements, which is critical for maintaining focus and operational efficiency in tasks like construction digging, mining loading, and infrastructure maintenance.

   Engineered to match original equipment performance standards, it maintains structural stability and comfort even under harsh working conditions, such as intense cabin vibration, temperature fluctuations, and occasional impact. It features a durable, easy-to-clean surface that resists wear from daily use and dust accumulation. Backed by strict performance verification, it guarantees long-term comfort and reliability to support uninterrupted operator productivity.
