This European Standard specifies requirements for butterfly valves having metallic bodies for use in flanged or
butt welding piping systems and used for isolating, regulating or control applications.
The PN and Class ranges are:
PN 2,5 ; PN 6 ; PN 10 ; PN 16 ; PN 25 ; PN 40 ; Class 150 ; Class 300.
The DN range is:
DN 20 ; DN 25 ; DN 32 ; DN 40 ; DN 50 ; DN 65 ; DN 80 ; DN 100 ; DN 125 ; DN 150 ; DN 200 ; DN 250 ;
DN 300 ; DN 350 ; DN 400 ; DN 450 ; DN 500 ; DN 600 ; DN 700 ; DN 750 ; DN 800 ; DN 900 ; DN 1000 ;
DN 1200 ; DN 1400 ; DN 1600 ; DN 1800 ; DN 2000 ; DN 2200 ; DN 2400.
DN 750 is used only for Class 150 and Class 300.
For special application as industrial process control valves, see EN 1349 and EN 60534-2-1.
