🔍 Key Concepts

• Pilot-operated pressure regulating valve behavior (main diaphragm chamber vs. pilot valve) • Role of the handle E and pilot valve F–G in controlling pressure above diaphragm I • How a blocked vs. leaking passage (B, C, or H) would affect pressure in the control chamber and therefore flow

💭 Think About

• Trace the normal flow path from INLET (II) to OUTLET, including how water gets into and out of chamber I above the main diaphragm. • For each labeled part in the options, ask: would this problem tend to make the main valve stay more open or more closed? Which condition matches excessive, continuous flow? • Decide whether the valve fails open or fails closed when pressure above diaphragm I is lost, and which fault listed would create that condition.

✅ Before You Answer

• Be clear on which passage or part controls pressure in chamber I (above diaphragm I). • Verify which items (B, C, H) would cause a loss of pressure in chamber I and which would cause a buildup of pressure there. • Confirm the function of handle E and the pilot valve F–G: does holding E in its actuated position increase or decrease pressure above diaphragm I?
