Where is information on valve ratings generally not found?

Valves have specific ratings that determine their performance characteristics, such as pressure tolerance and flow capacity. This information is typically included in various resources, but model codes do not always provide detailed information about valve ratings.

User manuals often contain comprehensive instructions and specifications related to the operation and maintenance of the valve, including its ratings. Industry standards are established guidelines set by organizations that dictate quality and safety specifications, which typically encompass valve ratings. Product specifications directly detail various attributes of the valve, including the ratings necessary for proper use.

In contrast, model codes are regulatory frameworks that specifically focus on operational parameters and compliance requirements rather than providing detailed technical specifications like valve ratings. Therefore, it's less common to find detailed valve ratings within model codes compared to other sources.
