🔍 Key Concepts

• Identify whether this is a pressure-reducing or pressure-relief type valve, and how outlet pressure is sensed and fed back to the main valve. • Trace the small passages from outlet to ports C and J and see which side of the diaphragm/piston they act on (opening vs. closing the main valve). • Consider what an auxiliary valve (D) leaking would do to the control pressure above or below the main diaphragm/piston and how that would change the outlet pressure.

💭 Think About

• When port C is plugged, does outlet pressure still reach the sensing element? If not, will the main valve tend to open more or close more? How does that affect outlet pressure? • If port J is plugged, is pressure trapped somewhere in the control chamber? Would trapped pressure tend to force the main valve more open or more closed? What does that do to outlet pressure? • If auxiliary valve D leaks, which chamber (above or below the diaphragm/piston) will lose pressure or gain pressure? Will that make the main valve move toward a more open or more closed position?

✅ Before You Answer

• Verify which side of the main diaphragm/piston is connected to port C and which side is connected to port J. • Determine whether a blockage at C or J removes outlet-pressure feedback or prevents pressure from being released/relieved, and whether that naturally makes the valve over‑reduce or under‑reduce. • Confirm whether a leak at auxiliary valve D would tend to equalize pressures between two chambers or vent one chamber, and how that changes the force balance controlling the outlet pressure.

Question 1 of 20

According to the illustration shown, which of the following statements is/are true? See illustration GS-0044.

If port "C" became obstructed or plugged, the outlet pressure would tend to decrease.

If port "J" became obstructed or plugged, the outlet pressure would tend to increase.

If auxiliary valve "D" developed a considerable leak, the outlet pressure would tend to increase.

all of the above
