🔍 Key Concepts

• Hydraulic line symbols vs. valve/orifice symbols in standard schematic drawings • How a check valve is usually shown (directional one-way flow element) • How a variable orifice or choke is shown (restriction whose size can change)

💭 Think About

• Study Fig. B: Does the symbol suggest a one-way device, or does it suggest a changing restriction in both directions? • Compare Fig. B to Fig. F in the same plate: which one looks more like a device that clearly allows flow in only one direction? • Think about how an orifice or choke affects flow: how might a draftsman show a narrowing or adjustable passage using curves or angled lines?

✅ Before You Answer

• Be sure you can picture the standard check-valve symbol (usually has a clear seat and a movable element pointing in one direction). • Confirm whether Fig. B shows symmetry about the vertical line or a clear arrow for directionality—this tells you if it is one‑way or two‑way. • Eliminate any option that represents a spring element or a distinctly mechanical device rather than a fluid passage restriction.
