所有尺寸的单位均为英寸。
STD = 标准壁厚
XS = 超强壁厚
XXS = 双倍超强壁厚
All Dimensions given in inches.
STD = Standard Wall Thickness
XS = Extra Strong Wall Thickness
XXS = Double Extra Strong Wall Thickness		 　　注意：阀体端口并没有包括足够的额外材料来适应所有目录管道的壁厚。目录中的x号表示不需要更改即可提供各种通径和压力等级的阀体。如果需要其它焊接端口，请咨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 weld ends.
