本节提供定制执行机构阀门组件包的型号编制规则。通过3个步骤来确定定制执行机构阀门型号。
　　The section is provided for formulation of part numbers on custom actuated valve packages. A 3-step process is used to build custom actuated valve part numbers:

　　步骤1 - 从相应的阀门选型表中选择所需要阀门的类型，款式，备选件和材质。从所提供的通径代码中确定阀门公称通径。
　　Step 1 - Select the desired type, style, options and material of valve from appropriate Valve Selection Table. Specify nominal valve size from Size Code available.
　　步骤2 - 从执行器选型表中选择所需要的执行器类型备选件。
　　Step 2 - Select the desired actuator style options from the Actuator Selection Tables.
　　步骤3 - 从附件选型表中选择所需要的执行器附件。
　　Step 3 - Select desired actuator accessories (if any) from the Accessories Selection Tables.

　　重要提示：定制附件要从执行机构阀门组件包独立型号下进行订购。附件型号单独订购，并且与所选择的执行机构阀门组件包一起由工厂组装。
　　IMPORTANT: Custom accessories are ordered under a separate part numbere from the actuated Valve Package. Accessory part numbers are ordered individually and factory assembled with selected Actuated Valve Package.
　　如果订购任何附件，则在执行机构阀门组件包型号末端加上后缀“A”。这个后缀只有在附件被选择后才增加在最初的执行机构阀门组件包上。
　　If any accessories are being ordered, add the suffix, "A" to the end of the Actuated Valve Package part number. This suffix is added only if an Accessory(s) is being selected for add on to the initial Actuated Valve Package.

　　Step 1: Valve & Size Code Selection
　　美国斯毕尔公司执行机构阀门选型表包括球阀（选型表1），蝶阀（选型表2），隔膜阀（选型表3）和闸阀（选型表3A）。利用表中的资料完成组件包型号中的阀门代码。
　　Spears® actuated valve selection table include Ball Valves (Selection Table 1), Butterfly Valves (Selection Table 2), Diaphragm Valves (Selection Table 3) and Gate Valves (Selection Table 3A). Use the table information to complete the Valve Code in the package part number.

　　Notes:

1. 只可提供的常规真活接结构通径DN15 ~ DN100的聚丙烯阀门，只有螺纹或SR螺纹端口连接件。DN15 ~ DN50通径的PVC和CPVC材质真活接阀门订购为“承插”，与承插和常规螺纹端口连接件一起提供。DN65 ~ DN150通径阀门则仅与承插一起提供。
   PP valves available in regular True Union style sizes ¹/₂" - 4" only, with threaded or SR threaded end connectors only. ¹/₂" - 2" PVC & CPVC True Union valves ordered as "socket" come with both socket and regular threaded end connectors. 2¹/₂" - 6" valves come with socket only.
2. 所有球阀都采用无硅树脂润滑剂组装。
   All Ball Valve are assembled with non-silicone lubricant.
3. 串联（转向）型号包括两个阀门由一个执行器驱动，在一个关闭时另一个开启。
   Tandem (Diverting) part number includes two valves operated from one actuator with one opening while the other closes.
