A primer on selecting & sizing of safety valves

摘要

here are several different factors which need to be taken into consideration before choosing any particular type of valve. For a non critical application, the most obvious one is price. It should be noted that when making price comparisons capacity must be taken into consideration (indicated by) the Kdr or (value) as well as nominal size since there can be large variations between models with the same inlet connection but varying lift characteristics.
