🔍 Key Concepts

• Study where labels D and I are located in relation to the inlet, outlet, and valve disk. • Think about how a pressure‑balanced valve is arranged so that changes in supply pressure do not force the valve disk open or closed. • Distinguish between parts that respond to temperature (bulb, bellows, spring) and parts that respond to steam pressure around the valve disk.

💭 Think About

• Trace the force path: which parts actually move the valve disk up or down, and which parts simply expose surfaces of the disk or plug to steam pressure? • If the inlet pressure suddenly increases, what would happen to the valve disk without parts D and I? Then ask what adding those parts would accomplish. • Which option describes a function that depends on temperature change, and which options describe a function that depends mainly on pressure balance or storage?

✅ Before You Answer

• Confirm whether D and I are in direct mechanical contact with the temperature-sensing linkage (bulb, bellows, lever) or only provide pressure surfaces around the plug/disk. • Verify which side of the valve disk sees inlet pressure and which spaces around D and I see the same pressure—this is key to understanding if they balance forces. • Make sure the chosen option matches a role that could be performed by static chambers or surfaces, not by moving linkages or springs tied to temperature.
