Abstract
A pressure relief valve (), having: an upper housing () defining a housing internal chamber () and comprising at least one window () between the upper housing chamber and the atmosphere; a lower housing () comprising a housing opening (); a pallet () disposed within the housing internal chamber; and a pair of nested springs () disposed within the housing internal chamber and configured to bias the pallet toward the lower housing and thereby form a seal () between the housing opening and the housing internal chamber. When the pressure in the housing opening is at a full discharge pressure that is greater than and within fourteen percent of the start-to-discharge pressure, the pair of nested springs is configured to permit the pallet to travel a sufficient distance to expose a flow area of the at least one window that is at least greater than a flow area () of the housing opening.
