The main feed check valve functions to __________.

Question 1 of 27070

The main feed check valve functions to __________.

🔍 Key Concepts

• main feed check valve location in a boiler feed system • Normal flow direction of feedwater between pump and boiler • What happens in the system if the feed pump suddenly stops while the boiler is under pressure

💭 Think About

• Picture the piping between the feed pump and the boiler: which component must protect the boiler if the pump fails? • Ask what the word "check" usually means for a valve in fluid systems. • Consider which option describes flow direction control rather than pressure reduction, pulsation smoothing, or adding head.

✅ Before You Answer

• Identify which choice clearly involves preventing reverse flow. • Eliminate any options that describe pressure control rather than flow direction control. • Verify which answer matches the typical function of a check valve in any piping system, not just boilers.
