Welcome anand !
If u want to know about the function and types. I
think you should refer to the vendor catalogues or
Handbooks.
1) Piping Handbook by Niar 2) Piping Handbook by Rodger and Hunt 3) Audco India valves 4) Velan 5) ABV valves 6) Goodwin International
We have design codes but u will find vendor catalogues more informative and easy to understand
Regards
