API602 Table F1 1

[SabirPakistani]

One question came up during globe valve vendor evaluation so please guide me:
• We need 2”-150# Globe valve A216 WCB Trim#1 (13CR) BB-OS&Y RF-SERR-FCG BS EN 10204 Type-3.1
• API602 table 12 gives us the trim#1 material details
• Now we have table F1 in same code which shows trim#8 for body material A216 WCB, under what conditions I shall use this table F1 since it shows different trim material. Although the trim#8 is also suitable for my case.

Table F1 does not specify trim. It only has a column for the Trim type that is typical for each valve type (what you will most likely find in vendors stock). You can have different trims.

Table F1 is mainly used as a guide for the body-bonnet bolting material.

In most cases customers will accept Trim 8 over trim 1. But please make sure with the end user.
