This pressure relief system drains the air inside to space if the pressure exceeds 1 atm, which can be used to guard against accidental station overpressure events. A passive vent inside (1) is connected to the control and the inlet. Another passive vent in space (2) is connected to the outlet. Since the outlet pressure is 0 kPa, then the pneumatic valve will only be on if the inside pressure exceeds 1 atm. When that happens, air from inside is transferred into space until the inside pressure is equal to 1 atm. | This pressure relief system drains the air inside to space if the pressure exceeds 1 atm, which can be used to guard against accidental station overpressure events.
