🔍 Key Concepts

• Standard valve symbols used in marine piping and P&ID diagrams • How a check valve, globe valve, relief valve, and motor‑operated valve are normally drawn • What a cluster of parallel loads/outlets on a hydraulic or lubrication diagram usually represents

💭 Think About

• Look closely at symbol 4: does it look like a single valve body, or a group of several identical elements arranged in parallel? • Compare symbol 4 with the clear valve symbols elsewhere in the same diagram (items 1, 2a, 2b, 6, 7, 8). Which of the answer choices share that same general shape? • Ask yourself which of the four valve types is normally shown as one discrete valve rather than as a bank or manifold of outlets.

✅ Before You Answer

• Verify how a check valve is drawn (usually a triangle against a line, showing flow in one direction). • Verify that a globe valve and relief valve each have distinct internal shapes on P&IDs and normally appear as single symbols, not a stack of many. • Confirm whether a motor operated valve symbol typically includes an actuator or motor marking on top of an otherwise standard valve symbol, rather than many parallel circles.
