The pilot-operated relief valve DB15G-2-L5X/5U/2 can achieve rapid pressure regulation and overload protection in the backup oil circuit through precise pressure sensing and pilot control mechanism. When the main oil circuit is abnormal and the pressure rises suddenly, the pilot valve responds quickly and triggers the main valve to open, releasing excess pressure energy, avoiding damage to the backup system due to overpressure, and ensuring its stability and reliability during emergency switching. Its dynamic response characteristics are particularly suitable for oil pressure safety protection of key equipment in power plants, providing the system with instant pressure balancing capabilities.

 

In the fault isolation function, the relief valve DB15G-2-L5X/5U/2 can accurately cut off the connection between the fault area and the main oil circuit through pressure feedback and rapid closing characteristics, preventing local abnormalities from spreading to the entire system. For example, when the backup oil pump unexpectedly shuts down or the pipeline leaks, the valve can quickly isolate the fault point, maintain the pressure stability of other branches, and provide a safe window for maintenance. This selective isolation capability reduces the risk of cascading failures and ensures the continuous operation of the core equipment of the power plant.

 

The emergency response and fault isolation technology of the overflow valve DB15G-2-L5X/5U/2 strengthens the risk resistance of the power plant's backup oil system through structured pressure control and fast actuators. Its design takes into account both stability under high-pressure conditions and the need for rapid decision-making under fault scenarios, becoming a key component to ensure safe switching and reliable backup of units.
