Valve Trim No.
Valve Trim No.
(OP)
I ran into some valve specifications where the trim of the valve is described as 'Trim 5' or 'Trim 8'. What are these numbers? I understand that the valve trim numbers correspond to the numbers in API-600 Table 3 or API-602
Table 4
Anybody can help me find these tables?
Thx

RE: Valve Trim No.
And when you look there you'll find, among others, the following trim numbers:
1 13Cr/13Cr (13Cr=410=CA15 cast= F6 forged)
5 HF/HF (HF=hardface=stellite)
8 13Cr/HF
9 Monel/Monel
10 316/316
11 Monel/HF
12 316/HF
(You can order the standards through the American Petroleum website, www.api.org, which refers you to www.global.ihs.com)
