适用范围：This part of IEC 60534 applies to the following control valves: - types: segmented ball and eccentric rotary control valves with or without flanges; - nominal sizes: DN20 up to and including DN400; NOTE 1 See ISO 7005 and ISO 6708. - designations: PN10, PN16, PN20, PN25, PN40, PN50, PN63, PN100 and PN110. NOTE 2 See ISO 7005 and ISO 7268. NOTE 3 Designations PN63 and PN100 are not included in ISO 7005. NOTE 4 Designations PN20, PN50 and PN110 are not included in European Standard EN 1092. NOTE 5 For the purposes of face-to-face dimensions, designation PN100 in EN 1092 corresponds to PN110. NOTE 6 For the purposes of face-to-face dimensions, the following correlations apply: - PN20 covers Classes 125 and 150 in the ANSI system; - PN50 covers Classes 250 and 300 in the ANSI system; - PN110 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.
