Abstract
A pressure relief valve assembly includes a rupture disc that is shaped to only be inserted into a particular rupture disc cavity in the correct way. The rupture disc includes a cylindrical rupture disc stem and a radially protruding upper lip. A relief valve body in the pressure relief assembly includes an internal radial shoulder at the entrance of the rupture disc that is narrower than the protruding upper lip of the rupture disc but that is wider than the rupture disc stem. The shoulder allows only the rupture disc stem to be inserted into the rupture disc cavity, not the protruding upper lip. Optionally, the relief valve body is marked with some indicia to indicating the direction of inserting the rupture disc stem and/or a shrapnel catcher for trapping shrapnel of the rupture disc upon rupturing.
