How can I determine the ASME B16.34 PT rating of a ball valve if an unlisted material like ASTM A694 F60 is used for the body?
Is there any calculation method that can be used on any ASME codes?
In a valve data sheet I found ZCMS 66 specified as seat and spring material. I didn't any International standard referring to it. Does anybody know if this is a specific manufacturer standard or what it is? Thanks.
