Webb21 juli 2024 · A safety valve opens quickly and fully, often “popping” open, due to static upstream pressure, and is often used with compressible fluids. A relief valve opens when static upstream pressure is higher than the opening pressure, and it opens in proportion to the pressure increase. This type of valve is more often used with incompressible fluids. Webb9 nov. 2009 · Then they will determine the maximum allowable working pressure (MAWP) of the vessel, and if it’s an API vessel, stamp that MAWP value right onto the vessel’s nameplate. The fabricator will ensure that the MAWP is greater than or equal to the design pressure. If you know the MAWP, you can have the relief valve set pressure = MAWP.
