30" 900lb Ring Joint face to face dimension??

[ValveNerd]

Trying to find the face to face dimension for a 30 inch 900lb class ring type joint. ASME B16.doesn't specify. 'm thinking this is because there is no specification for such a large valve, however ASME does provide an adder for such a large valve.

What gives? And while we're at it, what might be the face to face on a valve of this size and class?

thx,
Nick

With the info given in B16.47, Table 3, you should be able to get what you want with a little addition and subtraction.

The best bet though would be to call the valve vendor.

Thanks guys,

I have inquired with my supplier but I wanted to see what anyone's experiences might have shown. They haven't gotten back yet so it's good to have a rough est. Guess I'll find out soon enough.
thx!
