🔍 Key Concepts

• Look for the standard piping symbol of a valve with a small motor symbol (M) attached to it. • Compare the symbols for items 1, 2a/2b, 3, and 4 and notice which ones are clearly valves versus other components like pumps or manifolds. • Remember that a motor‑operated valve is still a valve symbol, but with an added actuator symbol indicating it is powered, not hand‑operated.

💭 Think About

• Which numbered items on the drawing are clearly valve symbols, and which are something else like a pump, strainer, or manifold? • Among the valve symbols, which one has an additional marking that indicates a motor or powered actuator rather than a handwheel? • How does the symbol for item 4 differ functionally from a single valve symbol—does it represent one valve or a group/distribution device?

✅ Before You Answer

• Verify which item numbers have the classic valve body symbol in the line and then see which of those has the "M" actuator symbol above it. • Confirm that items 2a and 2b are plain manual valves with no motor or actuator symbol attached. • Check that item 4 represents a bank or manifold rather than a single in‑line valve before making your final choice.
