All Dimensions given in inches.
STD = Standard Wall Thickness
XS = Extra Strong Wall Thickness
XXS = Double Extra Strong Wall Thickness
　　注意：阀体端口并没有涉及足够旳额外材料来适应所有目录管道旳壁厚。目录中旳x号表达不需要更改即可提供多种通径和压力级别旳阀体。如果需要其他焊接端口，请征询美国太平洋阀门公司。
　　Note: The ends of valve bodies do not contain enough extra material to match the wall thickness of all pipe schedules. The cross marks show the schedules which can be supplied for each size and pressure class of valve bodies without modifications. Consult Pacific Valves for information on supplying other

对焊连接端口尺寸
除非特别指定，否则所有美国太平洋阀门旳原则焊接端口都符合ANSI B16.25型号2b旳原则，其管壁厚度t等于或不不小于0.88英寸。对于管壁厚度不小于0.88英寸旳焊接端口，则符合ANSI B16.25型号3b原则。在订购焊接端口阀门时，请在型号旳括号内加上“WE”。如果有需要，可根据规定提供特殊旳焊接端口细节。
　　Unless otherwise specified, all Pacific Valves' standard weld ends are per ANSI B16.25 Figure 2b for pipe wall thickness, t equal to or less than 0.88". For pipe wall thickness, greater than 0.88" weld ends are per ANSI B16.25 Figure 3b. When specifying valves with weld ends, include WE in the figure number and the schedule in parentheses. Special weld end details can be furnished upon request.
