🔍 Key Concepts

• Purpose and function of a stop-check valve in a boiler feed system • Normal flow path of feedwater from condensate to the boiler drum • Which point in the system most needs backflow prevention and isolation close to the boiler

💭 Think About

• Think about what a stop-check valve can do that a regular stop valve or a regular check valve alone cannot, and where that combination is most useful in a boiler feed line. • Mentally trace the feedwater path: condenser → heaters → DC heater → economizer → boiler. At which point is it most critical to prevent flow from reversing back into the feed line? • Which location is immediately upstream of the boiler pressure boundary, where you would want both isolation and automatic non-return protection?

✅ Before You Answer

• Verify which component is closest to the boiler proper in the feed line among the answer choices. • Confirm where boiler non-return protection is normally fitted in typical marine boiler diagrams. • Check that the chosen location logically needs both manual shutoff (stop) and automatic backflow prevention (check) in one valve body.
