(OP)
wath is the meaning of number from presure class simbol (150, 300,...)?
is there a link between the number from presure class and work pressure?

RE: pressure class

Yes, there is a link.

See ASME B16.34 (valves) and/or B16.5 (flanges).

RE: pressure class

There is a link. The working pressure also varies with material and temperature of the fluid that will run thru.

You should check the ASME's StevenHPerry pointed out.

If you would like a guide for some materials follow the link.
