🔍 Key Concepts

• Look closely at where the "6" arrow is pointing in relation to the main vertical fitting and the side connection. • Think about how fluid would flow through this device: from the main line, past the sensing element, and then out to another part of the system. • Distinguish between a local component inside the body (like a filter or glass) and an external piping connection.

💭 Think About

• Trace the direction of the arrows that show the path of the fluid. Does the part labeled "6" appear to be inside the body or an external connection to another pipe? • Compare the shape and position of "6" with the side opening leading away from the main body. Which option from the list best describes that feature in a piping system? • Ask yourself which option (strainer, sight glass, drain, branch line) would usually be represented as a side connection off a main flow path in a sectional drawing like this.

✅ Before You Answer

• Verify whether the label "6" is pointing to piping leading away from the main body, not to a small internal piece. • Confirm that a sight glass is normally shown where you visually observe fluid level, not down in the valve body like this. • Check if a drain would usually be located at the lowest point of the assembly, whereas the part marked "6" is on the side, at mid‑height.
