WebbAbstract. Pressure relief valve or PRV is an important feature in the chemical process industries. Its objective is to provide a protective measure against overpressure scenario in equipment such as pressure vessel. This paper provides a fundamental description on the sizing of a single-phase pressure relief valve calculation. Webb1 mars 2024 · In simple terms, a relief valve is a device designed to control the pressure in a vessel or system to a specific set level. A safety valve, on the other hand, is a device used to let go excess pressure from a vessel or equipment when the pressure crosses a certain predetermined limit. It simply allows liquids or gases to escape if the pressure ...
