   SPARKLING MACHINERY NEW EC135B EC140B EC160B EC180B VOE14514195 Relay is a dedicated electrical control component for VOLVO EC135B, EC140B, EC160B, and EC180B crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As a core part of the excavator’s electrical system, it acts as a “signal switch” to control power supply for key devices (e.g., lights, fans, hydraulic valves)—ensuring stable operation of auxiliary and core functions during tasks like digging, loading, and equipment maneuvering.
   Meeting VOLVO OEM standards (part no. VOE14514195), it endures -30°C to 85°C temperatures, resists vibration and electrical interference, and maintains reliable switching performance. Strict testing guarantees seamless compatibility with the four VOLVO models and long-term electrical system stability.

The Volvo Swing Motor Valve Assembly (VOE 14558299 / 14558299 / 14775509 / 14672659) is a high‑precision relief/control valve engineered for the swing motor circuit in medium-to-large Volvo excavators—ranging from EC200B, EC235D, ECR235D to EC300D models. This valve regulates hydraulic pressure and protects the swing motor from overload, ensuring smooth 360° rotation and safe operation. Manufactured to OEM standards, it offers both genuine and premium aftermarket options that fit directly and restore reliable machine performance.

   SPARKLING MACHINERY NEW 2420-1125A Valve; By-Pass 4.5B is a dedicated hydraulic pressure regulation component for Doosan excavators (widely used in construction, mining, and municipal engineering). As the "hydraulic pressure buffer", it diverts excess hydraulic oil back to the tank when system pressure reaches 4.5B (bar) — preventing overpressure damage to pumps, valves, and cylinders during tasks like digging, lifting, and rock breaking, while ensuring stable oil flow for critical operations.
   Meeting Doosan OEM standards (part no. 2420-1125A), it maintains precise pressure control (4.5B set threshold), endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and ensures leak-free performance. Strict testing guarantees seamless compatibility with applicable Doosan models and long-term hydraulic system safety.
