WebPressure relief. Excess pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system. The relief valve is designed or set to open at a predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits. When the set pressure is … WebCommonly known simply as "records" in their era of greatest popularity (c. 1896–1916), these hollow cylindricalobjects have an audio recording engraved on the outside surface, which can be reproduced when they are played on a mechanical cylinder phonograph.[1]
