European standard for face-to-face of valves

[dfteng]

What is the prevailing European standard for face-to-face of check valves - both wafer and flanged? Is EN 558 the standard or is there another?

EN 558 is the standard for "Face-to-Face and Centre-to-Face Dimensions of Metal Valves for Use in Flanged Pipe". So at least the flanged valves are covered by this.

Here's the official European standard's web page:

Hope this helps!
