Arkansas Boiler Operator Practice Exam

What type of maintenance is required for control valves in boilers?

1. Regular inspection, cleaning, and calibration

2. Replacement every year

3. Only lubrication as needed

4. Inspection every five years

The correct answer is: Regular inspection, cleaning, and calibration

Control valves in boilers play a critical role in regulating the flow of steam or water, which directly impacts the boiler's efficiency and safety. Regular inspection, cleaning, and calibration of control valves are essential maintenance practices to ensure they function correctly. This type of maintenance helps to identify any wear and tear, prevents malfunctions, and ensures that the valves respond accurately to system demands. Regular inspections allow operators to detect any potential issues such as leaks, sticking mechanisms, or incorrect seating. Cleaning removes any debris or buildup that could obstruct the valve's operation. Calibration ensures that the valves open and close at the correct pressures and flows, maintaining the desired operational parameters. This comprehensive approach to maintenance helps enhance boiler performance and prolong the lifespan of the control valves, making it a best practice in boiler management. While other options might suggest maintenance practices, they do not encompass the ongoing and multifaceted care that control valves require for optimal performance.
