High Pressure lube oil is supplied to which component in the MFP system?

High-pressure lube oil is primarily supplied to control valves in the Main Feedwater Pump (MFP) system. This is because control valves are critical in regulating the flow and pressure of fluids within the system, and they require a reliable and consistent source of lubrication to ensure smooth operation. High-pressure lube oil helps to minimize friction and wear on the moving parts of these valves, which is essential for maintaining their performance and longevity.

Lube oil plays a significant role in preventing corrosion and overheating, ensuring that the control valves operate efficiently and respond accurately to changes in system conditions. By maintaining proper lubrication, the system can achieve optimal performance, thus supporting the overall reliability and safety of the auxiliary equipment in the MFP system.
