Question 1 of 27070

On a boiler equipped with pilot actuated safety valves, which of the valves listed will be actuated first?

🔍 Key Concepts

• Pilot-actuated safety valve sequence in boiler systems • Relationship between pilot valves and the main safety valves they control • Protection priorities between superheater and drum in overpressure situations

💭 Think About

• Think about which component actually SENSES the pressure first in a pilot-actuated safety valve arrangement. • Ask yourself: does the pilot valve open before or after the main safety valve it controls? • Consider which part of the boiler needs the most immediate protection from overpressure: the drum or the superheater, and how the pilot fits into that sequence.

✅ Before You Answer

• Identify which choice represents a pilot valve versus a main safety valve. • Confirm which device must lift first in order for a spring-loaded main safety valve to open. • Verify the usual safety priority in boiler design: protecting superheater tubes versus protecting the steam drum.
