The technical depth of API 553 provides engineers with a roadmap for mitigating risks associated with valve failure. One of the central themes of the document is the distinction between "tight shutoff" requirements and the operational reality of the process fluid. It classifies leakage classes (referencing ANSI/FCI 70-2) and guides engineers on how to specify the appropriate class based on the hazard potential of the fluid being controlled.
