What pressure do PRSOVs limit the pneumatic system to?

Explanation:
PRSOVs are used to clamp the pneumatic system pressure at a safe, predictable level so the actuators and other components receive consistent power and aren’t damaged by excess bleed air pressure. The regulated pressure is typically about 45 psi, with a tolerance of roughly +/- 3 psi, so you’d normally see 42 to 48 psi. The other options fall outside this established range, which is why they aren’t correct—the system is designed to limit pressure to about 45 psi to maintain proper operation and protect components.
