This part of lEG 60534 applies to the following control valves:
— types: segmented ball and eccentric rotary control valves with or without flanges;
— nominal sizes: DN2O up to and including DN400;
NOTE 1 See ISO 7005 and ISO 6708.
— designations: PN1O, PN16. PN2O, PN25. PN4O. PN5O. PN63, PNIOO and PN11O.
NOTE 2 See ISO 7005 and ISO 7268.
NOTE 3 Designations PN63 and PNIOO are not included In ISO 7005.
NOTE 4 Designations PN2O, PN5O and PN1 10 are not included in European Standard EN 1092,
NOTE 5 For the purposes of face-to-f ace dimensions, designation PN100 in EN 1092 corresponds to PN1IO.
NOTE 6 For the purposes of face-to-face dimensions, the following correlations apply
— PN2O covers Classes 125 and 150 In the ANSI system:
— PN5O covers Classes 250 and 300 in the ANSI system;
— PN1 10 covers Class 600 in the ANSI system.
Only raised face flanges are covered.
Specifically excluded from this standard are all valves having welded or threaded end connections.
