Ball Valve Regular Pattern

[gaoms84]

Hi,

Is ball valve with regular pattern avialable?
Is this pattern used for Ball valve.

Generally Long and short pattern are avialable for ball valve. But in my project, feed document which we recieved from client says Ball valve with regular pattern as per API 6D.

So, is this pattern applicable?


Thanks

gaoms84, API 6D doesn't use the term "regular pattern" with regard to ball valves, but your client obviously doesn't want "short pattern", which is the only alternative to the standard dimensions provided. Table 4 only lists dimensions for "Full-bore and reduced-bore", and "Short-pattern, full-bore and reduced-bore" ball valves up to Class 300.
Cheers,
John
