🔍 Key Concepts

• Understand the difference between a check valve (one-way flow, automatic) and a stop valve (manually opened/closed) and how a stop-check valve combines both functions. • Recognize that piping symbols often show a combination of features when a valve does more than one job (for example, a check symbol plus something that indicates manual operation). • Compare each symbol in the illustration and look for which one clearly shows both directional control and positive shutoff capability.

💭 Think About

• Which symbol looks most like a basic check valve symbol (two opposing triangles) and then ask: which one has an added feature that could represent a manual stop or globe-type element? • Look at each choice and ask: does this symbol show only one function (just flow direction OR just shutoff), or does it clearly suggest two functions combined into one valve? • Think about how a draftsman might modify a plain check-valve symbol to indicate that you can also close it by hand—what extra marking would make sense?

✅ Before You Answer

• Identify which symbol represents a plain check valve only and eliminate it, since a stop-check valve must do more than that. • Identify which symbol represents a plain stop (globe) valve and eliminate it for the same reason. • Before choosing, confirm that your remaining option clearly suggests both non-return action and manual shutoff in a single symbol.
