Full Description

BS EN 558:2008 specifies the face-to-face (FTF) and centre-to-face (CTF) dimensions for PN and Class designated metal valves used in flanged pipe systems.

BS EN 558:2008 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.
