   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 EC160B EC180B EC210B EC240B EC290B EC330B EC360B VOE120459960 Pully is a dedicated, heavy-duty mechanical component exclusively engineered for VOLVO EC160B, EC180B, EC210B, EC240B, EC290B, EC330B, and EC360B crawler excavators—versatile mid-to-large equipment widely used in construction, mining, and infrastructure maintenance projects. As a core part of the excavator’s power transmission and accessory drive system, it enables smooth belt operation to power critical auxiliary components (e.g., water pumps, alternators, hydraulic oil coolers). This function is vital for maintaining stable engine and hydraulic system performance during high-intensity tasks such as rock breaking, bulk material loading, and deep excavation, preventing belt slippage or drive system failures that could disrupt workflows.

   Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE120459960, the pully withstands harsh working conditions: high rotational speeds (up to 3,000 RPM), extreme temperature fluctuations (-25°C to 110°C), and continuous vibration from heavy-duty use. It maintains precise belt alignment and resists wear, ensuring long-lasting reliability for the excavators’ drive systems. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for the seven VOLVO excavator models.

   SPARKLING MACHINERY NEW EC220D EC235D EC250D EC250E EC300D 14592299 Relief Valve is a dedicated hydraulic safety component for VOLVO EC220D/EC235D/EC250D/EC250E/EC300D crawler excavators (heavy-duty equipment for construction/mining). As the hydraulic system’s core safety guard, it precisely limits max pressure to protect pumps, cylinders, and pipelines from overload damage during rock breaking or bulk loading.

   Meeting VOLVO OEM standards (part no. 14592299), it endures 34 MPa pressure, -25°C to 105°C temps, and heavy vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing compatibility and safe operation.
