Ball Vallve Calculation Design Handbook/Literatur.

[ketrab88]

HI all,

I am currently looking for a literature related to the Ball Valve design ( metal to metal & soft seated) ? But I am actually as well interested in Gate, Choke valves

I've found so far this link to the calculation sheet, which is actually brilliant -

It was posted here, in this thread:

I need something more detailed than this. Maybe someone knows a book/ standard which gives you the formula to calculate those kind of things depending whether is Metal seated, soft seated, ietc

Any help would be more than appreciated.

Thank you,
Bartosz
