API 6A- Face to Face for over 7-1/16
API 6A- Face to Face for over 7-1/16
(OP)
Hello All,
API 6A covers face to face dimensions only up to 7-1/16 Ball valve size.
Is there any other standard, I can refer to, for 2000 to 20000 PSI Ball valves?
Appreciate your comments.
Thanks

I have never heard of a 7-1/16" Ball valve or any other type valve for that matter.

For 10K, 15K and 20K valves, there are no international standards defining F/F or E/E length. Most end-users expect "manufacturer standard" in this case. Additionally, since there are no standards in the larger bore sizes for these pressures, and due to the weight involved, most end-users will specify the use of either Weld-End or compact hub connections such as Grayloc, Taper-Lok, or Norsok L-005. In specifying a WE valve, there is no need for a standard E/E length, because the piping will just be butting direct to valve anyway, and if the valve needs to be replaced, an entire section of piping will be cut out for the replacement. When using a hub type connection, the design is generally looking for additional weight-savings, so they are as short as the manufacturer can make them...again, to their own standard.
Hope that helps.

Certainly answered my question.
