Trim Selection
Trim Selection
(OP)
Hi All, I am trying to determine choice of trim for a valve...products are clean (mostly dry pentanes), valve is currently trim 8, I am being asked for trim 5, and the pipe spec calls for trim 12, what is the basis of a trim selection? is it mostly for material degradation??

Not sure if this is the case in your situation but when I see a valve spec that calls for Trim 12 and the customer asks for trim 5 what they actually want often times is trim 16 which is 316 sst with full stellite. Many customers don't understand/forget the stem is defined in the trim number. They just use trim 5 to mean full stellite seats forgetting it also means a 13%Cr Stem
