Valve trim chart notes.
The api 600 norm defined standard numbers to indentify the trim in terms of combinations of materials for the replaceable parts of the valve.
The installation of this type of valve creates a modest pressure drop in the pipeline lower than globe valves.
This will element the requirement of defining material grade for each component.
Always consult current api publications to verify information and trim data.
The trim shall be selected carefully depending on process parameters as fluid working temperature pressure and valve type.
The trim of a valve is the set of replaceable parts of a valve.
Api 600 602 gives the list of trim material that can be used in the valve.
