Valve Leak Detection and Monitoring

Cycle isolation refers to valve leakage losses that bypass the generation process. This type of valve leakage is one of the largest and often most overlooked issues in nuclear, fossil, and CCGT power plants. Curtiss-Wright's Cycle Isolation Monitoring module (available as an independent software solution or as a part of the FAMOS product suite) presents real-time data in a web-based platform that quickly detects cycle isolation issues and estimates leakage and heat rate impacts for each leaking valve. Curtiss-Wright's Cycle Isolation Monitoring module uses advanced temperature and stream calculations to provide an accurate representation of where efficiency improvements exist in a system. The valve leak detection platform generates data that can determine if a system has a weak point, pinpoint which section of the system may need to be replaced, and compare the cost of continued operation versus repair - allowing users to make informed decisions about the health and efficiency of their systems.


Combining real-time data and web browser displays, the Cycle Isolation Monitoring module quickly detects valve leak issues and automatically estimates the leakage rate along with power generation and heat rate impacts for each leaking valve.

The Cycle Isolation Monitoring module uses downstream temperature data to create valve leak alerts. Additional tools allow users to set up automatic notifications, alarms, and reports that are delivered to users and captured in the historian.

By offering critical insight into valve performance, the Cycle Isolation Monitoring module allows power plants to balance MW losses against planned outages and determine the most effective maintenance scheduling based on their individual needs.
