ATR General Familiarization Practice Test

Understanding how a pressure regulating valve operates helps here: such valves use hysteresis, meaning they open at a higher pressure and close at a lower pressure to avoid rapid on/off cycling. The given behavior states it opens at 3533 and closes at 3133. The statement that matches this exactly is the one that says it opens at 3533 and closes at 3133. The other possibilities would either reverse the thresholds, claim it never closes, or describe closing at the higher value and opening at the lower value, which doesn’t fit the described behavior.
