EN 558-1-2017 Valve Face to Face/End to End Dimension Comparison & Mirror to ASME/ANSI, EN/BS, API, EN/DINEN 558-1-2017 Valve Face to Face/End to End Dimension Comparison & Mirror

EN 558-1-2017 compares references face to face and centre to face dimensions major standards and allocates each one with a series number as shown in Table 1. Table 2 shows the face to face/end to end and centre to end/centre to face dimensions of each series number. Table 4 to 14 cross references the series number by valve type for each standard. ASME B16.10 table numbers referenced to in EN 558-1-2017 shown in Table 1 were originally table numbers used in ASME B16.10 1986. As of ASME B16.10-2007 the table numbers started to change. EN 558-1 still shows the original B16.10 1986 table/column numbers shown only as a source reference in Table 1 below. In the notes on the right hand side of Table 1 the description of the ASME B16.10 valve type & class etc. is shown.
