SPARKLING EC200B Relief Valve - Reliable Excavator Hydraulic Part

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 R250LC7 R250LC7A 31EN-10071 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R250LC7 and R250LC7A excavators. As a critical part of the swing system, it reduces engine speed to generate high torque, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during positioning, material handling, and precision operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under heavy rotational loads and continuous use. With optimized gear meshing design for minimal noise and wear, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW EC250D EC250E EC300D EC300E PL3005D 14591251 Relief Valve is a dedicated hydraulic safety component for VOLVO EC250D, EC250E, EC300D, EC300E, and PL3005D crawler excavators (heavy-duty equipment for mining, large-scale construction, and infrastructure projects). As the core safety guard of the hydraulic system, it precisely limits maximum pressure to protect pumps, cylinders, and pipelines from overload damage during rock breaking, bulk ore loading, and deep excavation.

   Meeting VOLVO OEM standards (part no. 14591251), it endures 34 MPa pressure, -25°C to 105°C temperature fluctuations, and continuous vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing seamless compatibility and safe operation.

   SPARKLING MACHINERY NEW EC140C EC140D EC140E EC160C 14577310 Toggle Switch is a key operator control component for Volvo EC140C, EC140D, EC140E, and EC160C excavators (widely used in construction, municipal engineering, and light mining). As the "operator command interface", it enables quick activation/deactivation of critical functions—such as wiper systems, auxiliary lights, or hydraulic tool controls—during tasks like digging, material handling, and site cleanup. This ensures intuitive operation for operators, while preventing accidental function misactivation and maintaining smooth workflow.
   Meeting Volvo OEM standards (part no. 14577310), it endures -30°C to 85°C temperatures, resists dust, moisture, and vibration, and guarantees reliable switch contact. Strict testing ensures seamless compatibility with the four Volvo models and long-term control system reliability.
