标准范围

IEC 60534-3-1:20 19规定了法兰、双向、球形、直型和角型控制阀的给定标称尺寸和压力等级的面对面（FTF）和中心面对面（CTF）尺寸。第二版取消并取代了2000年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)本标准已扩展至涵盖控制阀PN 160和PN 250（900和1500级）的面对面尺寸和中心面对面尺寸b)对于具有法兰面的阀门，增加了端到端尺寸和中心到端尺寸的定义，其中垫圈接触表面不位于阀门的最末端c)表5，末端-增加了带环形接头端的直型阀门的端到端尺寸d)在表1至4中增加了ANSI/ISA参考文献e)参考书目中增加了ANSI/ISA参考文献

IEC 60534-3-1:2019 specifies face-to-face (FTF) and centre-to-face (CTF) dimensions for given nominal sizes and pressure ratings of flanged, two-way, globe-type, straight pattern and angle pattern control valves This second edition cancels and replaces the first edition published in 2000. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) This standard has been extended to cover face-to-face dimensions and centre-to-face dimensions for control valves PN 160 and PN 250 (Class 900 and 1500)
b) Definitions of end-to-end dimensions and centre-to-end dimensions have been added for valves with flange facings where the gasket contact surfaces are not located at the extreme ends of the valve
c) Table 5 of adjustment value "X" for end-to-end dimensions of straight pattern valves with ring joint ends has been added
d) ANSI/ISA references have been added in Tables 1 to 4
e) ANSI/ISA references have been added in the bibliography
