Hi, I'm from Italy and I have a question about EN 593.
At point 4.2.3.1 of EN 593 it's indicated the maximum flow velocity of fluid in a butterfly valve. In the column of gaseos fluid there is the indication (at 1 bar). My question is: is the velocity limit indicated the limit of gaseos fluid at any pression? Has a gas at 5 bar and a gas at 2 bar the same velocity limit?
Thank you in advance,
Fabio
