A boiler feed stop-valve must be mounted __________.

🔍 Key Concepts

• Boiler feed system flow path: feed pump → feed stop-valve → feed check valve → boiler drum • Different functions of a feed stop-valve vs a feed check valve • Why engineers need to be able to isolate the boiler from the feed system quickly and safely

💭 Think About

• First, sketch or visualize the normal direction of flow from the feed pump all the way into the boiler drum. Where in that line would a shut‑off (stop) valve be most useful? • Ask yourself: which component directly protects the boiler from uncontrolled feed, and which component is used to simply shut off or isolate the feed line? • Think about maintenance or an emergency: which side of the feed check valve should the stop‑valve be on so the boiler can be safely isolated while still allowing work on the upstream system?

✅ Before You Answer

• Verify the sequence of components in a typical marine boiler feed line • Be clear on the difference in purpose between a stop‑valve (isolation) and a check valve (prevents backflow) • Confirm where the valve must be mounted so you can isolate the boiler itself, not just the pump or regulator
