Refinery fluids frequently subject control elements to extreme stress. API RP 553 provides targeted solutions to prevent sudden valve failures caused by fluid dynamics:
API 553 provides a standardized methodology to prevent these events. The PDF version is highly sought after because engineers need to reference specific tables, checklists, and inspection intervals while performing field work or writing standard operating procedures (SOPs).
: It emphasizes that EBVs and their control stations should be located outside fire zones to ensure they can be operated remotely during an emergency.

However, industry discussions often conflate API 553 with the broader family of valve standards, including:
The , officially titled "Refinery Valves and Accessories for Control and Safety Instrumented Systems," is a vital industry document providing recommended practices for the selection, specification, and application of automated valves in refinery services. Overview of API RP 553
The standard provides criteria for selecting the appropriate valve type (globe, butterfly, etc.) based on process requirements.
