Quoting 777WT (Reply 2): There's postive and negative relief valves for that.
These are not relief valves.The b752 has Two Negative relief valves on the RH side of the MEC area & Two Positive Pressure Valves on the LH Aft side near the Rear pressure bulkhead.
This is some structural part by the tone of the name I guess.
