This European Standard specifies the face to face (FTF) and centre to face (CTF) dimensions for PN and Class designated metal valves used in flanged pipe systems. This standard covers valves with the following PN, Class and DN values:  PN 2,5; PN 6; PN 10; PN 16; PN 25; PN 40; PN 63; PN 100; PN 160; PN 250; PN 320; PN 400; PN 500  Class 125; Class 150; Class 250; Class 300; Class 600; Class 900; Class 1 500; Class 2 500.  DN 10; DN 15; 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 1 000; DN 1 200; DN 1 400; DN 1 600; DN 1 800; DN 2 000. The face-to-face dimensions of flanged automatic steam traps are specified in EN 26554. For valves in other shell materials than metal the same FTF and CTF dimensions may be used.
